## Introduction

cmake-modules - Reference of available CMake modules.

## Description

The "cmake" executable is the CMake command-line interface. It may be used to configure projects in scripts. Project configuration settings may be specified on the command line with the -D option. The -i option will cause cmake to interactively prompt for such settings.

CMake is a cross-platform build system generator. Projects specify their build process with platform-independent CMake listfiles included in each directory of a source tree with the name CMakeLists.txt. Users build a project by using CMake to generate a build system for a native tool on their platform.

The following modules are provided with CMake. They can be used with INCLUDE(ModuleName).

      CMake Modules - Modules coming with CMake, the Cross-Platform Makefile Generator.

This is the documentation for the modules and scripts coming with CMake. Using these modules you can check the computer system for installed software packages, features of the compiler and the existance of headers to name just a few.

- `AddFileDependencies`: ADD_FILE_DEPENDENCIES(source_file depend_files...)

  Adds the given files as dependencies to source_file

- `BundleUtilities`:

  BundleUtilities.cmake

  A collection of CMake utility functions useful for dealing with .app bundles on the Mac and bundle-like directories on any OS.

  The following functions are provided by this script:

         get_bundle_main_executable
         get_dotapp_dir
         get_bundle_and_executable
         get_bundle_all_executables
         get_item_key
         clear_bundle_keys
         set_bundle_key_values
         get_bundle_keys
         copy_resolved_item_into_bundle
         fixup_bundle_item
         fixup_bundle
         copy_and_fixup_bundle
         verify_bundle_prerequisites
         verify_bundle_symlinks
         verify_app

  Requires CMake 2.6 or greater because it uses function, break and PARENT_SCOPE. Also depends on GetPrerequisites.cmake.

- `CMakeASM-ATTInformation`:

  support for AT&T syntax assemblers, e.g. GNU as

- `CMakeASM_MASMInformation`:

  support for the MS assembler, masm and masm64

- `CMakeBackwardCompatibilityCXX`: define a bunch of backwards compatibility variables

        CMAKE_ANSI_CXXFLAGS - flag for ansi c++
        CMAKE_HAS_ANSI_STRING_STREAM - has <strstream>
        INCLUDE(TestForANSIStreamHeaders)
        INCLUDE(CheckIncludeFileCXX)
        INCLUDE(TestForSTDNamespace)
        INCLUDE(TestForANSIForScope)

- `CMakeDependentOption`: Macro to provide an option dependent on other options.

  This macro presents an option to the user only if a set of other conditions are true. When the option is not presented a default value is used, but any value set by the user is preserved for when the option is presented again. Example invocation:

        CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON
                               "USE_BAR;NOT USE_ZOT" OFF)

  If USE_BAR is true and USE_ZOT is false, this provides an option called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for the USE_FOO option is saved so that when the option is re-enabled it retains its old value.

- `CMakeDetermineASM-ATTCompiler`:

  determine the compiler to use for ASM using AT&T syntax, e.g. GNU as

- `CMakeDetermineASMCompiler`:

  determine the compiler to use for ASM programs

- `CMakeDetermineASM_MASMCompiler`:

  Find the MS assembler (masm or masm64)

- `CMakeExportBuildSettings`: export build settings from a project.

        CMAKE_EXPORT_BUILD_SETTINGS(SETTINGS_FILE)

  macro defined to export the build settings for use by another project.

        SETTINGS_FILE - the file into which the settings are to be stored.

- `CMakeFindFrameworks`: helper module to find OSX frameworks
- `CMakeForceCompiler`:

  This module defines macros intended for use by cross-compiling toolchain files when CMake is not able to automatically detect the compiler identification.

  Macro CMAKE_FORCE_C_COMPILER has the following signature:

         CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>)

  It sets CMAKE_C_COMPILER to the given compiler and the cmake internal variable CMAKE_C_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

  Macro CMAKE_FORCE_CXX_COMPILER has the following signature:

         CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>)

  It sets CMAKE_CXX_COMPILER to the given compiler and the cmake internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests.

  So a simple toolchain file could look like this:

         INCLUDE (CMakeForceCompiler)
         SET(CMAKE_SYSTEM_NAME Generic)
         CMAKE_FORCE_C_COMPILER   (chc12 MetrowerksHicross)
         CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross)

- `CMakeImportBuildSettings`: import build settings from another project

        CMAKE_IMPORT_BUILD_SETTINGS(SETTINGS_FILE)

  macro defined to import the build settings from another project. SETTINGS_FILE is a file created by the other project's call to the CMAKE_EXPORT_BUILD_SETTINGS macro, see CMakeExportBuildSettings.

- `CMakeJavaInformation`:

  This should be included before the _INIT variables are used to initialize the cache. Since the rule variables have if blocks on them, users can still define them here. But, it should still be after the platform file so changes can be made to those values.

- `CMakePrintSystemInformation`: print system information

  This file can be used for diagnostic purposes just include it in a project to see various internal CMake variables.

- `CPack`: Build binary and source package installers

  The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new targets to the resulting makefiles, package and package_source, which build the binary and source installers, respectively. The generated binary installers contain everything installed via CMake's INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS commands).

  For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COMPONENT argument of CMake's INSTALL command. These components can be annotated with user-friendly names and descriptions, inter-component dependencies, etc., and grouped in various ways to customize the resulting installer. See the cpack_add_* commands, described below, for more information about component-specific installations.

  Before including the CPack module, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are:

         CPACK_PACKAGE_NAME - The name of the package (or application). If
         not specified, defaults to the project name.

         CPACK_PACKAGE_VENDOR - The name of the package vendor (e.g.,
         "Kitware").

         CPACK_PACKAGE_VERSION_MAJOR - Package major Version

         CPACK_PACKAGE_VERSION_MINOR - Package minor Version

         CPACK_PACKAGE_VERSION_PATCH - Package patch Version

         CPACK_PACKAGE_DESCRIPTION_FILE - A text file used to describe the
         project. Used, for example, the introduction screen of a
         CPack-generated Windows installer to describe the project.

         CPACK_PACKAGE_DESCRIPTION_SUMMARY - Short description of the
         project (only a few words).

         CPACK_PACKAGE_FILE_NAME - The name of the package file to generate,
         not including the extension. For example, cmake-2.6.1-Linux-i686.

         CPACK_PACKAGE_INSTALL_DIRECTORY - Installation directory on the
         target system, e.g., "CMake 2.5".

         CPACK_RESOURCE_FILE_LICENSE - License file for the project, which
         will typically be displayed to the user (often with an explicit
         "Accept" button, for graphical installers) prior to installation.

         CPACK_RESOURCE_FILE_README - ReadMe file for the project, which
         typically describes in some detail

         CPACK_RESOURCE_FILE_WELCOME - Welcome file for the project, which
         welcomes users to this installer. Typically used in the graphical
         installers on Windows and Mac OS X.

         CPACK_MONOLITHIC_INSTALL - Disables the component-based
         installation mechanism, so that all components are always installed.

         CPACK_GENERATOR - List of CPack generators to use. If not
         specified, CPack will create a set of options (e.g.,
         CPACK_BINARY_NSIS) allowing the user to enable/disable individual
         generators.

         CPACK_OUTPUT_CONFIG_FILE - The name of the CPack configuration file
         for binary installers that will be generated by the CPack
         module. Defaults to CPackConfig.cmake.

         CPACK_PACKAGE_EXECUTABLES - Lists each of the executables along
         with a text label, to be used to create Start Menu shortcuts on
         Windows. For example, setting this to the list ccmake;CMake will
         create a shortcut named "CMake" that will execute the installed
         executable ccmake.

         CPACK_STRIP_FILES - List of files to be stripped. Starting with
         CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which
         enables stripping of all files (a list of files evaluates to TRUE
         in CMake, so this change is compatible).

  The following CPack variables are specific to source packages, and will not affect binary packages:

         CPACK_SOURCE_PACKAGE_FILE_NAME - The name of the source package,
         e.g., cmake-2.6.1

         CPACK_SOURCE_STRIP_FILES - List of files in the source tree that
         will be stripped. Starting with CMake 2.6.0
         CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables
         stripping of all files (a list of files evaluates to TRUE in CMake,
         so this change is compatible).

         CPACK_SOURCE_GENERATOR - List of generators used for the source
         packages. As with CPACK_GENERATOR, if this is not specified then
         CPack will create a set of options (e.g., CPACK_SOURCE_ZIP)
         allowing users to select which packages will be generated.

         CPACK_SOURCE_OUTPUT_CONFIG_FILE - The name of the CPack
         configuration file for source installers that will be generated by
         the CPack module. Defaults to CPackSourceConfig.cmake.

         CPACK_SOURCE_IGNORE_FILES - Pattern of files in the source tree
         that won't be packaged when building a source package. This is a
         list of patterns, e.g., /CVS/;/\\.svn/;\\.swp$;\\.#;/#;.*~;cscope.*

  The following variables are specific to the graphical installers built on Windows using the Nullsoft Installation System.

         CPACK_PACKAGE_INSTALL_REGISTRY_KEY - Registry key used when
         installing this project.

         CPACK_NSIS_MUI_ICON - The icon file (.ico) for the generated
         install program.

         CPACK_NSIS_MUI_UNIICON - The icon file (.ico) for the generated
         uninstall program.

         CPACK_PACKAGE_ICON - A branding image that will be displayed inside
         the installer.

         CPACK_NSIS_EXTRA_INSTALL_COMMANDS - Extra NSIS commands that will
         be added to the install Section.

         CPACK_NSIS_EXTRA_UNINSTALL_COMMANDS - Extra NSIS commands that will
         be added to the uninstall Section.

         CPACK_NSIS_COMPRESSOR - The arguments that will be passed to the
         NSIS SetCompressor command.

         CPACK_NSIS_MODIFY_PATH - If this is set to "ON", then an extra page
         will appear in the installer that will allow the user to choose
         whether the program directory should be added to the system PATH
         variable.

         CPACK_NSIS_DISPLAY_NAME - The title displayed at the top of the
         installer.

         CPACK_NSIS_INSTALLED_ICON_NAME - A path to the executable that
         contains the installer icon.

         CPACK_NSIS_HELP_LINK - URL to a web site providing assistance in
         installing your application.

         CPACK_NSIS_URL_INFO_ABOUT - URL to a web site providing more
         information about your application.

         CPACK_NSIS_CONTACT - Contact information for questions and comments
         about the installation process.

         CPACK_NSIS_CREATE_ICONS_EXTRA - Additional NSIS commands for
         creating start menu shortcuts.

         CPACK_NSIS_DELETE_ICONS_EXTRA -Additional NSIS commands to
         uninstall start menu shortcuts.

  The following variable is specific to installers build on Mac OS X using PackageMaker:

         CPACK_OSX_PACKAGE_VERSION - The version of Mac OS X that the
         resulting PackageMaker archive should be compatible
         with. Different versions of Mac OS X support different
         features. For example, CPack can only build component-based
         installers for Mac OS X 10.4 or newer, and can only build
         installers that download component son-the-fly for Mac OS X 10.5
         or newer. If left blank, this value will be set to the minimum
         version of Mac OS X that supports the requested features. Set this
         variable to some value (e.g., 10.4) only if you want to guarantee
         that your installer will work on that version of Mac OS X, and
         don't mind missing extra features available in the installer
         shipping with later versions of Mac OS X.

  The following variables are for advanced uses of CPack:

         CPACK_CMAKE_GENERATOR - What CMake generator should be used if the
         project is CMake project. Defaults to the value of CMAKE_GENERATOR;
         few users will want to change this setting.

         CPACK_INSTALL_CMAKE_PROJECTS - List of four values that specify
         what project to install. The four values are: Build directory,
         Project Name, Project Component, Directory. If omitted, CPack will
         build an installer that installers everything.

         CPACK_SYSTEM_NAME - System name, defaults to the value of
         ${CMAKE_SYSTEM_NAME}.

         CPACK_PACKAGE_VERSION - Package full version, used internally. By
         default, this is built from CPACK_PACKAGE_VERSION_MAJOR,
         CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH.

         CPACK_TOPLEVEL_TAG - Directory for the installed files.

         CPACK_INSTALL_COMMANDS - Extra commands to install components.

         CPACK_INSTALL_DIRECTORIES - Extra directories to install.

  Component-specific installation allows users to select specific sets of components to install during the install process. Installation components are identified by the COMPONENT argument of CMake's INSTALL commands, and should be further described by the following CPack commands:

         cpack_add_component - Describes a CPack installation component
         named by the COMPONENT argument to a CMake INSTALL command.

           cpack_add_component(compname
                               [DISPLAY_NAME name]
                               [DESCRIPTION description]
                               [HIDDEN | REQUIRED | DISABLED ]
                               [GROUP group]
                               [DEPENDS comp1 comp2 ... ]
                               [INSTALL_TYPES type1 type2 ... ]
                               [DOWNLOADED]
                               [ARCHIVE_FILE filename])

         The cmake_add_component command describes an installation
         component, which the user can opt to install or remove as part of
         the graphical installation process. compname is the name of the
         component, as provided to the COMPONENT argument of one or more
         CMake INSTALL commands.

         DISPLAY_NAME is the displayed name of the component, used in
         graphical installers to display the component name. This value can
         be any string.

         DESCRIPTION is an extended description of the component, used in
         graphical installers to give the user additional information about
         the component. Descriptions can span multiple lines using "\n" as
         the line separator. Typically, these descriptions should be no
         more than a few lines long.

         HIDDEN indicates that this component will be hidden in the
         graphical installer, so that the user cannot directly change
         whether it is installed or not.

         REQUIRED indicates that this component is required, and therefore
         will always be installed. It will be visible in the graphical
         installer, but it cannot be unselected. (Typically, required
         components are shown greyed out).

         DISABLED indicates that this component should be disabled
         (unselected) by default. The user is free to select this component
         for installation, unless it is also HIDDEN.

         DEPENDS lists the components on which this component depends. If
         this component is selected, then each of the components listed
         must also be selected. The dependency information is encoded
         within the installer itself, so that users cannot install
         inconsitent sets of components.

         GROUP names the component group of which this component is a
         part. If not provided, the component will be a standalone
         component, not part of any component group. Component groups are
         described with the cpack_add_component_group command, detailed
         below.

         INSTALL_TYPES lists the installation types of which this component
         is a part. When one of these installations types is selected, this
         component will automatically be selected. Installation types are
         described with the cpack_add_install_type command, detailed below.

         DOWNLOADED indicates that this component should be downloaded
         on-the-fly by the installer, rather than packaged in with the
         installer itself. For more information, see the cpack_configure_downloads
         command.

         ARCHIVE_FILE provides a name for the archive file created by CPack
         to be used for downloaded components. If not supplied, CPack will
         create a file with some name based on CPACK_PACKAGE_FILE_NAME and
         the name of the component. See cpack_configure_downloads for more
         information.

         cpack_add_component_group - Describes a group of related CPack
         installation components.

           cpack_add_component_group(groupname
                                    [DISPLAY_NAME name]
                                    [DESCRIPTION description]
                                    [PARENT_GROUP parent]
                                    [EXPANDED]
                                    [BOLD_TITLE])

         The cpack_add_component_group describes a group of installation
         components, which will be placed together within the listing of
         options. Typically, component groups allow the user to
         select/deselect all of the components within a single group via a
         single group-level option. Use component groups to reduce the
         complexity of installers with many options. groupname is an
         arbitrary name used to identify the group in the GROUP argument of
         the cpack_add_component command, which is used to place a
         component in a group. The name of the group must not conflict with
         the name of any component.

         DISPLAY_NAME is the displayed name of the component group, used in
         graphical installers to display the component group name. This
         value can be any string.

         DESCRIPTION is an extended description of the component group,
         used in graphical installers to give the user additional
         information about the components within that group. Descriptions
         can span multiple lines using "\n" as the line
         separator. Typically, these descriptions should be no more than a
         few lines long.

         PARENT_GROUP, if supplied, names the parent group of this group.
         Parent groups are used to establish a hierarchy of groups,
         providing an arbitrary hierarchy of groups.

         EXPANDED indicates that, by default, the group should show up as
         "expanded", so that the user immediately sees all of the
         components within the group. Otherwise, the group will initially
         show up as a single entry.

         BOLD_TITLE indicates that the group title should appear in bold,
         to call the user's attention to the group.

         cpack_add_install_type - Add a new installation type containing a
         set of predefined component selections to the graphical installer.

           cpack_add_install_type(typename
                                  [DISPLAY_NAME name])

         The cpack_add_install_type command identifies a set of preselected
         components that represents a common use case for an
         application. For example, a "Developer" install type might include
         an application along with its header and library files, while an
         "End user" install type might just include the application's
         executable. Each component identifies itself with one or more
         install types via the INSTALL_TYPES argument to
         cpack_add_component.

         DISPLAY_NAME is the displayed name of the install type, which will
         typically show up in a drop-down box within a graphical
         installer. This value can be any string.

         cpack_configure_downloads - Configure CPack to download selected
         components on-the-fly as part of the installation process.

           cpack_configure_downloads(site
                                     [UPLOAD_DIRECTORY dirname]
                                     [ALL]
                                     [ADD_REMOVE|NO_ADD_REMOVE])

         The cpack_configure_downloads command configures installation-time
         downloads of selected components. For each downloadable component,
         CPack will create an archive containing the contents of that
         component, which should be uploaded to the given site. When the
         user selects that component for installation, the installer will
         download and extract the component in place. This feature is
         useful for creating small installers that only download the
         requested components, saving bandwidth. Additionally, the
         installers are small enough that they will be installed as part of
         the normal installation process, and the "Change" button in
         Windows Add/Remove Programs control panel will allow one to add or
         remove parts of the application after the original
         installation. On Windows, the downloaded-components functionality
         requires the ZipDLL plug-in for NSIS, available at:

           http://nsis.sourceforge.net/ZipDLL_plug-in

         On Mac OS X, installers that download components on-the-fly can
         only be built and installed on system using Mac OS X 10.5 or
         later.

         The site argument is a URL where the archives for downloadable
         components will reside, e.g., http://www.cmake.org/files/2.6.1/installer/
         All of the archives produced by CPack should be uploaded to that location.

         UPLOAD_DIRECTORY is the local directory where CPack will create the
         various archives for each of the components. The contents of this
         directory should be uploaded to a location accessible by the URL given
         in the site argument. If omitted, CPack will use the directory CPackUploads
         inside the CMake binary directory to store the generated archives.

         The ALL flag indicates that all components be downloaded. Otherwise, only
         those components explicitly marked as DOWNLOADED or that have a specified
         ARCHIVE_FILE will be downloaded. Additionally, the ALL option implies
         ADD_REMOVE (unless NO_ADD_REMOVE is specified).

         ADD_REMOVE indicates that CPack should install a copy of the installer
         that can be called from Windows' Add/Remove Programs dialog (via the
         "Modify" button) to change the set of installed components. NO_ADD_REMOVE
         turns off this behavior. This option is ignored on Mac OS X.

- `Dart`: Configure a project for testing with CTest or old Dart Tcl Client

  This file is the backwards-compatibility version of the CTest module. It supports using the old Dart 1 Tcl client for driving dashboard submissions as well as testing with CTest. This module should be included in the CMakeLists.txt file at the top of a project. Typical usage:

        INCLUDE(Dart)
        IF(BUILD_TESTING)
          # ... testing related CMake code ...
        ENDIF(BUILD_TESTING)

  The BUILD_TESTING option is created by the Dart module to determine whether testing support should be enabled. The default is ON.

- `Documentation`: DocumentationVTK.cmake

  This file provides support for the VTK documentation framework. It relies on several tools (Doxygen, Perl, etc).

- `FeatureSummary`: Macros for generating a summary of enabled/disabled features

  PRINT_ENABLED_FEATURES()

         Print a summary of all enabled features. By default all successfull
         FIND_PACKAGE() calls will appear here, except the ones which used the QUIET keyword.
         Additional features can be added by appending an entry to the global ENABLED_FEATURES
         property. If SET_FEATURE_INFO() is used for that feature, the output will be much
         more informative.

  PRINT_DISABLED_FEATURES()

         Same as PRINT_ENABLED_FEATURES(), but for disabled features. It can be extended
         the same way by adding to the global property DISABLED_FEATURES.

  SET_FEATURE_INFO(NAME DESCRIPTION [URL [COMMENT] ] )

          Use this macro to set up information about the named feature, which will
          then be displayed by PRINT_ENABLED/DISABLED_FEATURES().
          Example: SET_FEATURE_INFO(LibXml2 "XML processing library." "http://xmlsoft.org/")

- `FindASPELL`: Try to find ASPELL

  Once done this will define

        ASPELL_FOUND - system has ASPELL
        ASPELL_INCLUDE_DIR - the ASPELL include directory
        ASPELL_LIBRARIES - The libraries needed to use ASPELL
        ASPELL_DEFINITIONS - Compiler switches required for using ASPELL

- `FindAVIFile`: Locate AVIFILE library and include paths

  AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for i386 machines to use various AVI codecs. Support is limited beyond Linux. Windows provides native AVI support, and so doesn't need this library. This module defines

        AVIFILE_INCLUDE_DIR, where to find avifile.h , etc.
        AVIFILE_LIBRARIES, the libraries to link against
        AVIFILE_DEFINITIONS, definitions to use when compiling
        AVIFILE_FOUND, If false, don't try to use AVIFILE

- `FindBLAS`: Find BLAS library

  This module finds an installed fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/). The list of libraries searched for is taken from the autoconf macro file, acx_blas.m4 (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).

  This module sets the following variables:

        BLAS_FOUND - set to true if a library implementing the BLAS interface
          is found
        BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
          and -L).
        BLAS_LIBRARIES - uncached list of libraries (using full path name) to
          link against to use BLAS
        BLAS95_LIBRARIES - uncached list of libraries (using full path name)
          to link against to use BLAS95 interface
        BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
          is found
        BLA_STATIC  if set on this determines what kind of linkage we do (static)
        BLA_VENDOR  if set checks only the specified vendor, if not set checks
           all the posibilities
        BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK

  ######### ## List of vendors (BLA_VENDOR) valid in this module # ATLAS, PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread model, lp64 model), # Intel( older versions of mkl 32 and 64 bit), ACML,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl

- `FindBZip2`: Try to find BZip2

  Once done this will define

        BZIP2_FOUND - system has BZip2
        BZIP2_INCLUDE_DIR - the BZip2 include directory
        BZIP2_LIBRARIES - Link these to use BZip2
        BZIP2_DEFINITIONS - Compiler switches required for using BZip2
        BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_

- `FindBoost`: Try to find Boost include dirs and libraries

  Usage of this module as follows:

  == Using Header-Only libraries from within Boost: ==

         find_package( Boost 1.36.0 )
         if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
         endif()

  == Using actual libraries from within Boost: ==

         set(Boost_USE_STATIC_LIBS   ON)
         set(Boost_USE_MULTITHREADED ON)
         find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )

         if(Boost_FOUND)
            include_directories(${Boost_INCLUDE_DIRS})
            add_executable(foo foo.cc)
            target_link_libraries(foo ${Boost_LIBRARIES})
         endif()

  The components list needs to contain actual names of boost libraries only, such as "date_time" for "libboost_date_time". If you're using parts of Boost that contain header files only (e.g. foreach) you do not need to specify COMPONENTS.

  You should provide a minimum version number that should be used. If you provide this version number and specify the REQUIRED attribute, this module will fail if it can't find the specified or a later version. If you specify a version number this is automatically put into the considered list of version numbers and thus doesn't need to be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).

  NOTE for Visual Studio Users:

           Automatic linking is used on MSVC & Borland compilers by default when
           #including things in Boost.  It's important to note that setting
           Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
           should you need this feature.  Automatic linking typically uses static
           libraries with a few exceptions (Boost.Python is one).

           Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
           more details.  Adding a TARGET_LINK_LIBRARIES() as shown in the example
           above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
           gets set to OFF.  It is suggested you avoid automatic linking since it
           will make your application less portable.

  =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?) ============

  OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of boost version numbers that should be taken into account when searching for Boost. Unfortunately boost puts the version number into the actual filename for the libraries, so this variable will certainly be needed in the future when new Boost versions are released.

  Currently this module searches for the following version numbers: 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1, 1.36, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0

  NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS you should add both 1.x and 1.x.0 as shown above. Official Boost include directories omit the 3rd version number from include paths if it is 0 although not all binary Boost releases do so.

  SET(Boost_ADDITIONAL_VERSIONS "0.99" "0.99.0" "1.78" "1.78.0")

  ============================================================================

  Variables used by this module, they can change the default behaviour and need to be set before calling find_package:

         Boost_USE_MULTITHREADED      Can be set to OFF to use the non-multithreaded
                                      boost libraries.  If not specified, defaults
                                      to ON.

         Boost_USE_STATIC_LIBS        Can be set to ON to force the use of the static
                                      boost libraries. Defaults to OFF.

  Other Variables used by this module which you may want to set.

         Boost_ADDITIONAL_VERSIONS    A list of version numbers to use for searching
                                      the boost include directory.  Please see
                                      the documentation above regarding this
                                      annoying, but necessary variable :(

         Boost_DEBUG                  Set this to TRUE to enable debugging output
                                      of FindBoost.cmake if you are having problems.
                                      Please enable this before filing any bug
                                      reports.

         Boost_COMPILER               Set this to the compiler suffix used by Boost
                                      (e.g. "-gcc43") if FindBoost has problems finding
                                      the proper Boost installation

  Variables defined by this module:

         Boost_FOUND                         System has Boost, this means the include dir was
                                             found, as well as all the libraries specified in
                                             the COMPONENTS list.

         Boost_INCLUDE_DIR                   This is almost the same as above, but this one is
                                             cached and may be modified by advanced users

         Boost_LIBRARIES                     Link to these to use the Boost libraries that you
                                             specified: not cached

         Boost_LIB_VERSION                   The version number in filename form as
                                             it's appended to the library filenames

         Boost_MAJOR_VERSION                 major version number of boost

         Boost_SUBMINOR_VERSION              subminor version number of boost

         Boost_LIB_DIAGNOSTIC_DEFINITIONS    [WIN32 Only] You can call
                                             add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINTIIONS})
                                             to have diagnostic information about Boost's
                                             automatic linking outputted during compilation time.

  For each component you specify in find_package(), the following (UPPER-CASE) variables are set. You can use these variables if you would like to pick and choose components for your targets instead of just using Boost_LIBRARIES.

         Boost_${COMPONENT}_FOUND            True IF the Boost library "component" was found.

         Boost_${COMPONENT}_LIBRARY          Contains the libraries for the specified Boost
                                             "component" (includes debug and optimized keywords
                                             when needed).

  $GDALDIR is an environment variable that would correspond to the ./configure --prefix=$GDAL_DIR used in building gdal.

  Created by Eric Wing. I'm not a gdal user, but OpenSceneGraph uses it for osgTerrain so I whipped this module together for completeness. I actually don't know the conventions or where files are typically placed in distros. Any real gdal users are encouraged to correct this (but please don't break the OS X framework stuff when doing so which is what usually seems to happen).

        KDE3_BUILD_TESTS - enable this to build KDE testcases

  It also adds the following macros (from KDE3Macros.cmake) SRCS_VAR is always the variable which contains the list of source files for your application or library.

  KDE3_AUTOMOC(file1 ... fileN)

          Call this if you want to have automatic moc file handling.
          This means if you include "foo.moc" in the source file foo.cpp
          a moc file for the header foo.h will be created automatically.
          You can set the property SKIP_AUTOMAKE using SET_SOURCE_FILES_PROPERTIES()
          to exclude some files in the list from being processed.

  KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN )

          If you don't use the KDE3_AUTOMOC() macro, for the files
          listed here moc files will be created (named "foo.moc.cpp")

  KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h )

          Use this to generate DCOP skeletions from the listed headers.

  KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h )

           Use this to generate DCOP stubs from the listed headers.

  KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui )

          Use this to add the Qt designer ui files to your application/library.

  KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc )

          Use this to add KDE kconfig compiler files to your application/library.

  KDE3_INSTALL_LIBTOOL_FILE(target)

          This will create and install a simple libtool file for the given target.

  KDE3_ADD_EXECUTABLE(name file1 ... fileN )

          Currently identical to ADD_EXECUTABLE(), may provide some advanced features in the future.

  KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN )

          Create a KDE plugin (KPart, kioslave, etc.) from the given source files.
          If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't.
          It creates and installs an appropriate libtool la-file.

  KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN )

          Create a KDE application in the form of a module loadable via kdeinit.
          A library named kdeinit_<name> will be created and a small executable which links to it.

  The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no longer supported.

        LUA_LIBRARIES, both lua and lualib
        LUA_INCLUDE_DIR, where to find lua.h and lualib.h (and probably lauxlib.h)

  Note that the expected include convention is

        MPEG2_FOUND, If false, do not try to use MPEG2.

  also defined, but not for general use are

        MPEG2_mpeg2_LIBRARY, where to find the MPEG2 library.
        MPEG2_vo_LIBRARY, where to find the vo library.

- `FindMPI`: Message Passing Interface (MPI) module.

  The Message Passing Interface (MPI) is a library used to write high-performance parallel applications that use message passing, and is typically deployed on a cluster. MPI is a standard interface (defined by the MPI forum) for which many implementations are available. All of these implementations have somewhat different compilation approaches (different include paths, libraries to link against, etc.), and this module tries to smooth out those differences.

  This module will set the following variables:

         MPI_FOUND                  TRUE if we have found MPI
         MPI_COMPILE_FLAGS          Compilation flags for MPI programs
         MPI_INCLUDE_PATH           Include path(s) for MPI header
         MPI_LINK_FLAGS             Linking flags for MPI programs
         MPI_LIBRARY                First MPI library to link against (cached)
         MPI_EXTRA_LIBRARY          Extra MPI libraries to link against (cached)
         MPI_LIBRARIES              All libraries to link MPI programs against
         MPIEXEC                    Executable for running MPI programs
         MPIEXEC_NUMPROC_FLAG       Flag to pass to MPIEXEC before giving it the
                                    number of processors to run on
         MPIEXEC_PREFLAGS           Flags to pass to MPIEXEC directly before the
                                    executable to run.
         MPIEXEC_POSTFLAGS          Flags to pass to MPIEXEC after all other flags.

  This module will attempt to auto-detect these settings, first by looking for a MPI compiler, which many MPI implementations provide as a pass-through to the native compiler to simplify the compilation of MPI programs. The MPI compiler is stored in the cache variable MPI_COMPILER, and will attempt to look for commonly-named drivers mpic++, mpicxx, mpiCC, or mpicc. If the compiler driver is found and recognized, it will be used to set all of the module variables. To skip this auto-detection, set MPI_LIBRARY and MPI_INCLUDE_PATH in the CMake cache.

  If no compiler driver is found or the compiler driver is not recognized, this module will then search for common include paths and library names to try to detect MPI.

  If CMake initially finds a different MPI than was intended, and you want to use the MPI compiler auto-detection for a different MPI implementation, set MPI_COMPILER to the MPI compiler driver you want to use (e.g., mpicxx) and then set MPI_LIBRARY to the string MPI_LIBRARY-NOTFOUND. When you re-configure, auto-detection of MPI will run again with the newly-specified MPI_COMPILER.

  When using MPIEXEC to execute MPI applications, you should typically use all of the MPIEXEC flags as follows:

         ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE
           ${MPIEXEC_POSTFLAGS} ARGS

  where PROCS is the number of processors on which to execute the program, EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the MPI program.

- `FindMatlab`: this module looks for Matlab

  Defines:

        MATLAB_INCLUDE_DIR: include path for mex.h, engine.h
        MATLAB_LIBRARIES:   required libraries: libmex, etc

        MOTIF_LIBRARIES    - Link these to use Motif

- `FindOpenAL`:

  Locate OpenAL This module defines OPENAL_LIBRARY OPENAL_FOUND, if false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where to find the headers

        OPENGL_GLU_FOUND    - system has GLU
        OPENGL_INCLUDE_DIR  - the GL include directory
        OPENGL_LIBRARIES    - Link these to use OpenGL and GLU

  If you want to use just GL you can use these values

        OPENGL_gl_LIBRARY   - Path to OpenGL Library
        OPENGL_glu_LIBRARY  - Path to GLU Library

  On OSX default to using the framework version of opengl People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX

- `FindOpenMP`: Finds OpenMP support

  This module can be used to detect OpenMP support in a compiler. If the compiler supports OpenMP, the flags required to compile with openmp support are set.

  The following variables are set:

         OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support
         OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support
         OPENMP_FOUND - true if openmp is detected

  Supported compilers can be found at http://openmp.org/wp/openmp-compilers/

- `FindOpenSSL`: Try to find the OpenSSL encryption library

  Once done this will define

        OPENSSL_INCLUDE_DIR - the OpenSSL include directory
        OPENSSL_LIBRARIES - The libraries needed to use OpenSSL

- `FindOpenSceneGraph`: Find OpenSceneGraph

  This module searches for the OpenSceneGraph core "osg" library as well as OpenThreads, and whatever additional COMPONENTS that you specify.

          See http://www.openscenegraph.org

  NOTE: If you would like to use this module in your CMAKE_MODULE_PATH instead of requiring CMake >= 2.6.3, you will also need to download FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, as well as files for any Components you need to call (FindosgDB.cmake, FindosgUtil.cmake, etc.)

  ==================================

  This module accepts the following variables (note mixed case)

          OpenSceneGraph_DEBUG - Enable debugging output

          OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
                                            automatically

  The following environment variables are also respected for finding the OSG and it's various components. CMAKE_PREFIX_PATH can also be used for this (see find_library() CMake documentation).

          <MODULE>_DIR (where MODULE is of the form "OSGVOLUME" and there is a FindosgVolume.cmake file)
          OSG_DIR
          OSGDIR
          OSG_ROOT

  This module defines the following output variables:

          OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?

          OPENSCENEGRAPH_VERSION - The version of the OSG which was found

          OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers

          OPENSCENEGRAPH_LIBRARIES - The OSG libraries

  ================================== Example Usage:

        find_package(OpenSceneGraph 2.0.0 COMPONENTS osgDB osgUtil)
        include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})

        add_executable(foo foo.cc)
        target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})

  ==================================

  ==================================

- `FindOpenThreads`:

  OpenThreads is a C++ based threading library. Its largest userbase seems to OpenSceneGraph so you might notice I accept OSGDIR as an environment path. I consider this part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module.

  Locate OpenThreads This module defines OPENTHREADS_LIBRARY OPENTHREADS_FOUND, if false, do not try to link to OpenThreads OPENTHREADS_INCLUDE_DIR, where to find the headers

  $OPENTHREADS_DIR is an environment variable that would correspond to the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

  Created by Eric Wing.

- `FindPHP4`: Find PHP4

  This module finds if PHP4 is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PHP4_INCLUDE_PATH       = path to where php.h can be found
        PHP4_EXECUTABLE         = full path to the php4 binary

- `FindPNG`: Find the native PNG includes and library

  This module defines

        PNG_INCLUDE_DIR, where to find png.h, etc.
        PNG_LIBRARIES, the libraries to link against to use PNG.
        PNG_DEFINITIONS - You should ADD_DEFINITONS(${PNG_DEFINITIONS}) before compiling code that includes png library files.
        PNG_FOUND, If false, do not try to use PNG.

  also defined, but not for general use are

        PNG_LIBRARY, where to find the PNG library.

  None of the above will be defined unles zlib can be found. PNG depends on Zlib

- `FindPackageHandleStandardArgs`:

  FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )

          This macro is intended to be used in FindXXX.cmake modules files.
          It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
          it also sets the <UPPERCASED_NAME>_FOUND variable.
          The package is found if all variables listed are TRUE.
          Example:

          FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)

          LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
          LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
          If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
          independent whether QUIET was used or not.
          If it is found, the location is reported using the VAR1 argument, so
          here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
          If the second argument is DEFAULT_MSG, the message in the failure case will
          be "Could NOT find LibXml2", if you don't like this message you can specify
          your own custom failure message there.

- `FindPackageMessage`:

  FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")

  This macro is intended to be used in FindXXX.cmake modules files. It will print a message once for each unique find result. This is useful for telling the user where a package was found. The first argument specifies the name (XXX) of the package. The second argument specifies the message to display. The third argument lists details about the find result so that if they change the message will be displayed again. The macro also obeys the QUIET argument to the find_package command.

  Example:

        IF(X11_FOUND)
          FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
            "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
        ELSE(X11_FOUND)
         ...
        ENDIF(X11_FOUND)

- `FindPerl`: Find perl

  this module looks for Perl

        PERL_EXECUTABLE - the full path to perl
        PERL_FOUND      - If false, don't attempt to use perl.

- `FindPerlLibs`: Find Perl libraries

  This module finds if PERL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PERL_INCLUDE_PATH = path to where perl.h is found
        PERL_EXECUTABLE   = full path to the perl binary

- `FindPhysFS`:

  Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of the library to link against PHYSFS_FOUND, if false, do not try to link to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h

  $PHYSFSDIR is an environment variable that would correspond to the ./configure --prefix=$PHYSFSDIR used in building PHYSFS.

  Created by Eric Wing.

- `FindPike`: Find Pike

  This module finds if PIKE is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PIKE_INCLUDE_PATH       = path to where program.h is found
        PIKE_EXECUTABLE         = full path to the pike binary

- `FindPkgConfig`: a pkg-config module for CMake

  Usage:

         pkg_check_modules(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
           checks for all the given modules

         pkg_search_module(<PREFIX> [REQUIRED] <MODULE> [<MODULE>]*)
           checks for given modules and uses the first working one

  When the 'REQUIRED' argument was set, macros will fail with an error when module(s) could not be found

  It sets the following variables:

         PKG_CONFIG_FOUND         ... true if pkg-config works on the system
         PKG_CONFIG_EXECUTABLE    ... pathname of the pkg-config program
         <PREFIX>_FOUND           ... set to 1 if module(s) exist

  For the following variables two sets of values exist; first one is the common one and has the given PREFIX. The second set contains flags which are given out when pkgconfig was called with the '--static' option.

         <XPREFIX>_LIBRARIES      ... only the libraries (w/o the '-l')
         <XPREFIX>_LIBRARY_DIRS   ... the paths of the libraries (w/o the '-L')
         <XPREFIX>_LDFLAGS        ... all required linker flags
         <XPREFIX>_LDFLAGS_OTHER  ... all other linker flags
         <XPREFIX>_INCLUDE_DIRS   ... the '-I' preprocessor flags (w/o the '-I')
         <XPREFIX>_CFLAGS         ... all required cflags
         <XPREFIX>_CFLAGS_OTHER   ... the other compiler flags

         <XPREFIX> = <PREFIX>        for common case
         <XPREFIX> = <PREFIX>_STATIC for static linking

  There are some special variables whose prefix depends on the count of given modules. When there is only one module, <PREFIX> stays unchanged. When there are multiple modules, the prefix will be changed to <PREFIX>_<MODNAME>:

         <XPREFIX>_VERSION    ... version of the module
         <XPREFIX>_PREFIX     ... prefix-directory of the module
         <XPREFIX>_INCLUDEDIR ... include-dir of the module
         <XPREFIX>_LIBDIR     ... lib-dir of the module

         <XPREFIX> = <PREFIX>  when |MODULES| == 1, else
         <XPREFIX> = <PREFIX>_<MODNAME>

  A <MODULE> parameter can have the following formats:

         {MODNAME}            ... matches any version
         {MODNAME}>={VERSION} ... at least version <VERSION> is required
         {MODNAME}={VERSION}  ... exactly version <VERSION> is required
         {MODNAME}<={VERSION} ... modules must not be newer than <VERSION>

  Examples

         pkg_check_modules (GLIB2   glib-2.0)

         pkg_check_modules (GLIB2   glib-2.0>=2.10)
           requires at least version 2.10 of glib2 and defines e.g.
             GLIB2_VERSION=2.10.3

         pkg_check_modules (FOO     glib-2.0>=2.10 gtk+-2.0)
           requires both glib2 and gtk2, and defines e.g.
             FOO_glib-2.0_VERSION=2.10.3
             FOO_gtk+-2.0_VERSION=2.8.20

         pkg_check_modules (XRENDER REQUIRED xrender)
           defines e.g.:
             XRENDER_LIBRARIES=Xrender;X11
             XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp

         pkg_search_module (BAR     libxml-2.0 libxml2 libxml>=2)

- `FindProducer`:

  Though Producer isn't directly part of OpenSceneGraph, its primary user is OSG so I consider this part of the Findosg* suite used to find OpenSceneGraph components. You'll notice that I accept OSGDIR as an environment path.

  Each component is separate and you must opt in to each module. You must also opt into OpenGL (and OpenThreads?) as these modules won't do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

  Locate Producer This module defines PRODUCER_LIBRARY PRODUCER_FOUND, if false, do not try to link to Producer PRODUCER_INCLUDE_DIR, where to find the headers

  $PRODUCER_DIR is an environment variable that would correspond to the ./configure --prefix=$PRODUCER_DIR used in building osg.

- `FindPythonInterp`: Find python interpreter

  This module finds if Python interpreter is installed and determines where the executables are. This code sets the following variables:

        PYTHONINTERP_FOUND - Was the Python executable found
        PYTHON_EXECUTABLE  - path to the Python interpreter

- `FindPythonLibs`: Find python libraries

  This module finds if Python is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        PYTHONLIBS_FOUND     = have the Python libs been found
        PYTHON_LIBRARIES     = path to the python library
        PYTHON_INCLUDE_PATH  = path to where Python.h is found
        PYTHON_DEBUG_LIBRARIES = path to the debug library

- `FindQt`: Searches for all installed versions of QT.

  This should only be used if your project can work with multiple versions of QT. If not, you should just directly use FindQt4 or FindQt3. If multiple versions of QT are found on the machine, then The user must set the option DESIRED_QT_VERSION to the version they want to use. If only one version of qt is found on the machine, then the DESIRED_QT_VERSION is set to that version and the matching FindQt3 or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module is included.

        QT_REQUIRED if this is set to TRUE then if CMake can
                    not find QT4 or QT3 an error is raised
                    and a message is sent to the user.

        DESIRED_QT_VERSION OPTION is created
        QT4_INSTALLED is set to TRUE if qt4 is found.
        QT3_INSTALLED is set to TRUE if qt3 is found.

- `FindQt3`: Locate Qt include paths and libraries

  This module defines:

        QT_INCLUDE_DIR - where to find qt.h, etc.
        QT_LIBRARIES   - the libraries to link against to use Qt.
        QT_DEFINITIONS - definitions to use when
                         compiling code that uses Qt.
        QT_FOUND       - If false, don't try to use Qt.

  If you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE

  Also defined, but not for general use are:

        QT_MOC_EXECUTABLE, where to find the moc tool.
        QT_UIC_EXECUTABLE, where to find the uic tool.
        QT_QT_LIBRARY, where to find the Qt library.
        QT_QTMAIN_LIBRARY, where to find the qtmain
         library. This is only required by Qt3 on Windows.

- `FindQt4`: Find QT 4

  This module can be used to find Qt4. The most important issue is that the Qt4 qmake is available via the system path. This qmake is then used to detect basically everything else. This module defines a number of key variables and macros. The variable QT_USE_FILE is set which is the path to a CMake file that can be included to compile Qt 4 applications and libraries. It sets up the compilation environment for include directories, preprocessor defines and populates a QT_LIBRARIES variable.

  Typical usage could be something like:

         find_package(Qt4 4.4.3 COMPONENTS QtCore QtGui QtXml REQUIRED )
         include(${QT_USE_FILE})
         add_executable(myexe main.cpp)
         target_link_libraries(myexe ${QT_LIBRARIES})

  When using the components argument, QT_USE_QT* variables are automatically set for the QT_USE_FILE to pick up. If one wishes to manually set them, the available ones to set include:

                          QT_DONT_USE_QTCORE
                          QT_DONT_USE_QTGUI
                          QT_USE_QT3SUPPORT
                          QT_USE_QTASSISTANT
                          QT_USE_QAXCONTAINER
                          QT_USE_QAXSERVER
                          QT_USE_QTDESIGNER
                          QT_USE_QTMOTIF
                          QT_USE_QTMAIN
                          QT_USE_QTNETWORK
                          QT_USE_QTNSPLUGIN
                          QT_USE_QTOPENGL
                          QT_USE_QTSQL
                          QT_USE_QTXML
                          QT_USE_QTSVG
                          QT_USE_QTTEST
                          QT_USE_QTUITOOLS
                          QT_USE_QTDBUS
                          QT_USE_QTSCRIPT
                          QT_USE_QTASSISTANTCLIENT
                          QT_USE_QTHELP
                          QT_USE_QTWEBKIT
                          QT_USE_QTXMLPATTERNS
                          QT_USE_PHONON

  There are also some files that need processing by some Qt tools such as moc and uic. Listed below are macros that may be used to process those files.

        macro QT4_WRAP_CPP(outfiles inputfile ... OPTIONS ...)
              create moc code from a list of files containing Qt class with
              the Q_OBJECT declaration.  Per-direcotry preprocessor definitions
              are also added.  Options may be given to moc, such as those found
              when executing "moc -help".

        macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt designer ui files.
              Options may be given to uic, such as those found
              when executing "uic -help"

        macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...)
              create code from a list of Qt resource files.
              Options may be given to rcc, such as those found
              when executing "rcc -help"

        macro QT4_GENERATE_MOC(inputfile outputfile )
              creates a rule to run moc on infile and create outfile.
              Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g.
              because you need a custom filename for the moc file or something similar.

        macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... )
              This macro is still experimental.
              It can be used to have moc automatically handled.
              So if you have the files foo.h and foo.cpp, and in foo.h a
              a class uses the Q_OBJECT macro, moc has to run on it. If you don't
              want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert
              #include "foo.moc"
              in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will the
              scan all listed files at cmake-time for such included moc files and if it finds
              them cause a rule to be generated to run moc at build time on the
              accompanying header file foo.h.
              If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro.

        macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename)
              create a the interface header and implementation files with the
              given basename from the given interface xml file and add it to
              the list of sources

        macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... )
              create the interface header and implementation files
              for all listed interface xml files
              the name will be automatically determined from the name of the xml file

        macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] )
              create a dbus adaptor (header and implementation file) from the xml file
              describing the interface, and add it to the list of sources. The adaptor
              forwards the calls to a parent class, defined in parentheader and named
              parentclassname. The name of the generated files will be
              <basename>adaptor.{cpp,h} where basename is the basename of the xml file.

        macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] )
              generate the xml interface file from the given header.
              If the optional argument interfacename is omitted, the name of the
              interface file is constructed from the basename of the header with
              the suffix .xml appended.

        macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ...
                                      ts_files ... OPTIONS ...)
              out: qm_files
              in:  directories sources ts_files
              options: flags to pass to lupdate, such as -extensions to specify
              extensions for a directory scan.
              generates commands to create .ts (vie lupdate) and .qm
              (via lrelease) - files from directories and/or sources. The ts files are
              created and/or updated in the source tree (unless given with full paths).
              The qm files are generated in the build tree.
              Updating the translations can be done by adding the qm_files
              to the source list of your library/executable, so they are
              always updated, or by adding a custom target to control when
              they get updated/generated.

        macro QT4_ADD_TRANSLATION( qm_files ts_files ... )
              out: qm_files
              in:  ts_files
              generates commands to create .qm from .ts - files. The generated
              filenames can be found in qm_files. The ts_files
              must exists and are not updated in any way.

                         You do not need to use this if you include QT_USE_FILE.
                         The QT_USE_FILE will also define QT_DEBUG and QT_NO_DEBUG
                         to fit your current build type.  Those are not contained
                         in QT_DEFINITIONS.

        QT_INCLUDES      List of paths to all include directories of
                         Qt4 QT_INCLUDE_DIR and QT_QTCORE_INCLUDE_DIR are
                         always in this variable even if NOTFOUND,
                         all other INCLUDE_DIRS are
                         only added if they are found.
                         You do not need to use this if you include QT_USE_FILE.

        Include directories for the Qt modules are listed here.

  also defined, but NOT for general use are

        QT_MOC_EXECUTABLE          Where to find the moc tool.
        QT_UIC_EXECUTABLE          Where to find the uic tool.

  These are around for backwards compatibility they will be set

        QT_WRAP_CPP  Set true if QT_MOC_EXECUTABLE is found
        QT_WRAP_UI   Set true if QT_UIC_EXECUTABLE is found

  These variables do _NOT_ have any effect anymore (compared to FindQt.cmake)

        QT_MT_REQUIRED         Qt4 is now always multithreaded

  These variables are set to "" Because Qt structure changed (They make no sense in Qt4)

        QT_QT_LIBRARY        Qt-Library is now split

- `FindQuickTime`:

  Locate QuickTime This module defines QUICKTIME_LIBRARY QUICKTIME_FOUND, if false, do not try to link to gdal QUICKTIME_INCLUDE_DIR, where to find the headers

  $QUICKTIME_DIR is an environment variable that would correspond to the ./configure --prefix=$QUICKTIME_DIR

  Created by Eric Wing.

- `FindRTI`: Try to find M&S HLA RTI libraries

  This module finds if any HLA RTI is installed and locates the standard RTI include files and libraries.

  RTI is a simulation infrastructure standartized by IEEE and SISO. It has a well defined C++ API that assures that simulation applications are independent on a particular RTI implementation. http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation)

  This code sets the following variables:

        RTI_INCLUDE_DIR = the directory where RTI includes file are found
        RTI_LIBRARIES = The libraries to link against to use RTI
        RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM
        RTI_FOUND = Set to FALSE if any HLA RTI was not found

  Report problems to <certi-devel@nongnu.org>

- `FindRuby`: Find Ruby

  This module finds if Ruby is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        RUBY_INCLUDE_PATH = path to where ruby.h can be found
        RUBY_EXECUTABLE   = full path to the ruby binary
        RUBY_LIBRARY      = full path to the ruby library

- `FindSDL`:

  Locate SDL library This module defines SDL_LIBRARY, the name of the library to link against SDL_FOUND, if false, do not try to link to SDL SDL_INCLUDE_DIR, where to find SDL.h

  This module responds to the the flag: SDL_BUILDING_LIBRARY If this is defined, then no SDL_main will be linked in because only applications need main(). Otherwise, it is assumed you are building an application and this module will attempt to locate and set the the proper link flags as part of the returned SDL_LIBRARY variable.

  Don't forget to include SDLmain.h and SDLmain.m your project for the OS X framework based version. (Other versions link to -lSDLmain which this module will try to find on your behalf.) Also for OS X, this module will automatically add the -framework Cocoa on your behalf.

  Additional Note: If you see an empty SDL_LIBRARY_TEMP in your configuration and no SDL_LIBRARY, it means CMake did not find your SDL library (SDL.dll, libsdl.so, SDL.framework, etc). Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again. Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this value as appropriate. These values are used to generate the final SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY does not get created.

  $SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL. l.e.galup 9-20-02

  Modified by Eric Wing. Added code to assist with automated building by using environmental variables and providing a more controlled/consistent search behavior. Added new modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). Also corrected the header search path to follow "proper" SDL guidelines. Added a search for SDLmain which is needed by some platforms. Added a search for threads which is needed by some platforms. Added needed compile switches for MinGW.

  On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selection or set the CMake environment CMAKE_INCLUDE_PATH to modify the search paths.

  Note that the header path has changed from SDL/SDL.h to just SDL.h This needed to change because "proper" SDL convention is #include "SDL.h", not <SDL/SDL.h>. This is done for portability reasons because not all systems place things in SDL/ (see FreeBSD).

        SWIG_FOUND - set to true if SWIG is found
        SWIG_DIR - the directory where swig is installed
        SWIG_EXECUTABLE - the path to the swig executable

  The module defines the following variables:

        Subversion_SVN_EXECUTABLE - path to svn command line client
        Subversion_VERSION_SVN - version of svn command line client
        Subversion_FOUND - true if the command line client was found

  If the command line client executable is found the macro

        Subversion_WC_INFO(<dir> <var-prefix>)

  is defined to extract information of a subversion working copy at a given location. The macro defines the following variables:

        <var-prefix>_WC_URL - url of the repository (at <dir>)
        <var-prefix>_WC_ROOT - root url of the repository
        <var-prefix>_WC_REVISION - current revision
        <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit

          MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
        ENDIF(Subversion_FOUND)

- `FindTCL`: TK_INTERNAL_PATH was removed.

  This module finds if Tcl is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        TCL_FOUND              = Tcl was found
        TK_FOUND               = Tk was found
        TCLTK_FOUND            = Tcl and Tk were found
        TCL_LIBRARY            = path to Tcl library (tcl tcl80)
        TCL_INCLUDE_PATH       = path to where tcl.h can be found
        TCL_TCLSH              = path to tclsh binary (tcl tcl80)
        TK_LIBRARY             = path to Tk library (tk tk80 etc)
        TK_INCLUDE_PATH        = path to where tk.h can be found
        TK_WISH                = full path to the wish executable

  In an effort to remove some clutter and clear up some issues for people who are not necessarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are:

         => they were only useful for people writing Tcl/Tk extensions.
         => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs
            are created and there is no real reason to pick a single one
            specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx).
            Let's leave that choice to the user by allowing him to assign
            TCL_LIBRARY to any Tcl library, debug or not.
         => this ended up being only a Win32 variable, and there is a lot of
            confusion regarding the location of this file in an installed Tcl/Tk
            tree anyway (see 8.5 for example). If you need the internal path at
            this point it is safer you ask directly where the *source* tree is
            and dig from there.

- `FindTIFF`: Find TIFF library

  Find the native TIFF includes and library This module defines

        TIFF_INCLUDE_DIR, where to find tiff.h, etc.

  This module finds Tcl stub libraries. It first finds Tcl include files and libraries by calling FindTCL.cmake. How to Use the Tcl Stubs Library:

         http://tcl.activestate.com/doc/howto/stubs.html

  Using Stub Libraries:

         http://safari.oreilly.com/0130385603/ch48lev1sec3

        TK_STUB_LIBRARY        = path to Tk stub library
        TTK_STUB_LIBRARY       = path to ttk stub library

  In an effort to remove some clutter and clear up some issues for people who are not necessarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are:

         => these libs are not packaged by default with Tcl/Tk distributions.
            Even when Tcl/Tk is built from source, several flavors of debug libs

            Let's leave that choice to the user by allowing him to assign
            TCL_STUB_LIBRARY to any Tcl library, debug or not.

- `FindTclsh`: Find tclsh

  This module finds if TCL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables:

        TCLSH_FOUND = TRUE if tclsh has been found
        TCL_TCLSH = the path to the tclsh executable

  In cygwin, look for the cygwin version first. Don't look for it later to avoid finding the cygwin version on a Win32 build.

        VTK_FOUND         - Set to true when VTK is found.
        VTK_USE_FILE      - CMake file to use VTK.
        VTK_MAJOR_VERSION - The VTK major version number.
        VTK_MINOR_VERSION - The VTK minor version number
                             (odd non-release).
        VTK_BUILD_VERSION - The VTK patch level
                             (meaningless for odd minor).
        VTK_INCLUDE_DIRS  - Include directories for VTK
        VTK_LIBRARY_DIRS  - Link directories for VTK libraries
        VTK_KITS          - List of VTK kits, in CAPS

        VTK_LANGUAGES     - List of wrapped languages, in CAPS
                            (TCL, PYHTON,) etc.

  The following cache entries must be set by the user to locate VTK:

        VTK_DIR  - The directory containing VTKConfig.cmake.
                   This is either the root of the build tree,
                   or the lib/vtk directory.  This is the
                   only cache entry.

  The following variables are set for backward compatibility and should not be used in new code:

        USE_VTK_FILE - The full path to the UseVTK.cmake file.
                       This is provided for backward
                       compatibility.  Use VTK_USE_FILE
                       instead.

- `Findosg`:

  NOTE: It is highly recommended that you use the new FindOpenSceneGraph.cmake introduced in CMake 2.6.3 and not use this Find module directly.

  This is part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. You must also opt into OpenGL and OpenThreads (and Producer if needed) as these modules won't do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

  Locate osg This module defines

  This is part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. You must also opt into OpenGL and OpenThreads (and Producer if needed) as these modules won't do it for you. This is to allow you control over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

- `Findosg_functions`:

  This CMake file contains two macros to assist with searching for OSG libraries and nodekits.

- `FindwxWidgets`: Find a wxWidgets (a.k.a., wxWindows) installation.

  This module finds if wxWidgets is installed and selects a default configuration to use. wxWidgets is a modular library. To specify the modules that you will use, you need to name them as components to the package:

  FIND_PACKAGE(wxWidgets COMPONENTS base core ...)

  There are two search branches: a windows style and a unix style. For windows, the following variables are searched for and set to defaults in case of multiple choices. Change them if the defaults are not desired (i.e., these are the only variables you should change to select a configuration):

        wxWidgets_ROOT_DIR      - Base wxWidgets directory
                                  (e.g., C:/wxWidgets-2.6.3).
        wxWidgets_LIB_DIR       - Path to wxWidgets libraries
                                  (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
        wxWidgets_CONFIGURATION - Configuration to use
                                  (e.g., msw, mswd, mswu, mswunivud, etc.)

  For unix style it uses the wx-config utility. You can select between debug/release, unicode/ansi, universal/non-universal, and static/shared in the QtDialog or ccmake interfaces by turning ON/OFF the following variables:

        wxWidgets_USE_DEBUG
        wxWidgets_USE_UNICODE
        wxWidgets_USE_UNIVERSAL
        wxWidgets_USE_STATIC

  The following are set after the configuration is done for both windows and unix style:

        wxWidgets_FOUND            - Set to TRUE if wxWidgets was found.
        wxWidgets_INCLUDE_DIRS     - Include directories for WIN32
                                     i.e., where to find "wx/wx.h" and
                                     "wx/setup.h"; possibly empty for unices.
        wxWidgets_LIBRARIES        - Path to the wxWidgets libraries.
        wxWidgets_LIBRARY_DIRS     - compile time link dirs, useful for
                                     rpath on UNIX. Typically an empty string
                                     in WIN32 environment.
        wxWidgets_DEFINITIONS      - Contains defines required to compile/link
                                     against WX, e.g. -DWXUSINGDLL
        wxWidgets_CXX_FLAGS        - Include dirs and ompiler flags for
                                     unices, empty on WIN32. Esentially
                                     "`wx-config --cxxflags`".
        wxWidgets_USE_FILE         - Convenience include file.

  Sample usage:

         FIND_PACKAGE(wxWidgets COMPONENTS base core gl net)
         IF(wxWidgets_FOUND)
           INCLUDE(${wxWidgets_USE_FILE})
           # and for each of your dependant executable/library targets:
           TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
         ENDIF(wxWidgets_FOUND)

  If wxWidgets is required (i.e., not an optional part):

         FIND_PACKAGE(wxWidgets REQUIRED base core gl net)
         INCLUDE(${wxWidgets_USE_FILE})
         # and for each of your dependant executable/library targets:
         TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})

- `FindwxWindows`: Find wxWindows (wxWidgets) installation

  This module finds if wxWindows/wxWidgets is installed and determines where the include files and libraries are. It also determines what the name of the library is. Please note this file is DEPRECATED and replaced by FindwxWidgets.cmake. This code sets the following variables:

        WXWINDOWS_FOUND     = system has WxWindows
        WXWINDOWS_LIBRARIES = path to the wxWindows libraries
                              on Unix/Linux with additional
                              linker flags from
                              "wx-config --libs"
        CMAKE_WXWINDOWS_CXX_FLAGS  = Compiler flags for wxWindows,
                                     essentially "`wx-config --cxxflags`"
                                     on Linux
        WXWINDOWS_INCLUDE_DIR      = where to find "wx/wx.h" and "wx/setup.h"
        WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on
                                      Unix
        WXWINDOWS_DEFINITIONS      = extra defines

  OPTIONS If you need OpenGL support please

        SET(WXWINDOWS_USE_GL 1)

  in your CMakeLists.txt *before* you include this file.

        HAVE_ISYSTEM      - true required to replace -I by -isystem on g++

  For convenience include Use_wxWindows.cmake in your project's CMakeLists.txt using INCLUDE(Use_wxWindows).

  USAGE

        SET(WXWINDOWS_USE_GL 1)
        FIND_PACKAGE(wxWindows)

  NOTES wxWidgets 2.6.x is supported for monolithic builds e.g. compiled in wx/build/msw dir as:

        nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1

- `FortranCInterface`:

  FortranCInterface.cmake

  This file defines the function create_fortran_c_interface. this function is used to create a configured header file that contains a mapping from C to a Fortran function using the correct name mangling scheme as defined by the current fortran compiler.

  The function tages a list of functions and the name of a header file to configure.

  This file also defines some helper functions that are used to detect the fortran name mangling scheme used by the current Fortran compiler.

        test_fortran_mangling - test a single fortran mangling
        discover_fortran_mangling - loop over all combos of fortran
         name mangling and call test_fortran_mangling until one of them
         works.
        discover_fortran_module_mangling - try different types of
        fortran modle name mangling to find one that works

  this function tests a single fortran mangling. CODE - test code to try should define a subroutine called "sub" PREFIX - string to put in front of sub POSTFIX - string to put after sub ISUPPER - if TRUE then sub will be called as SUB DOC - string used in status checking Fortran ${DOC} linkage SUB - the name of the SUB to call RESULT place to store result TRUE if this linkage works, FALSE

              if not.

- `GetPrerequisites`:

  GetPrerequisites.cmake

  This script provides functions to list the .dll, .dylib or .so files that an executable or shared library file depends on. (Its prerequisites.)

  It uses various tools to obtain the list of required shared library files:

         dumpbin (Windows)
         ldd (Linux/Unix)
         otool (Mac OSX)

  The following functions are provided by this script:

         gp_append_unique
         gp_file_type
         is_file_executable
         gp_item_default_embedded_path
           (projects can override with gp_item_default_embedded_path_override)
         gp_resolve_item
           (projects can override with gp_resolve_item_override)
         get_prerequisites
         list_prerequisites
         list_prerequisites_by_glob

  Requires CMake 2.6 or greater because it uses function, break, return and PARENT_SCOPE.

- `ITKCompatibility`:

  work around an old bug in ITK prior to verison 3.0

- `InstallRequiredSystemLibraries`:

  By including this file, all files in the CMAKE_INSTALL_DEBUG_LIBRARIES, will be installed with INSTALL_PROGRAMS into /bin for WIN32 and /lib for non-win32. If CMAKE_SKIP_INSTALL_RULES is set to TRUE before including this file, then the INSTALL command is not called. The use can use the variable CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to use a custom install command and install them into any directory they want. If it is the MSVC compiler, then the microsoft run time libraries will be found add automatically added to the CMAKE_INSTALL_DEBUG_LIBRARIES, and installed. If CMAKE_INSTALL_DEBUG_LIBRARIES is set and it is the MSVC compiler, then the debug libraries are installed when available. If CMAKE_INSTALL_MFC_LIBRARIES is set then the MFC run time libraries are installed as well as the CRT run time libraries.

  It contains the following variables: ECOS_DEFINITIONS ECOSCONFIG_EXECUTABLE ECOS_CONFIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable for internal use only:

        ECOS_ADD_TARGET_LIB

- `UsePkgConfig`: obsolete pkg-config module for CMake

  Defines the following macros:

  PKGCONFIG(package includedir libdir linkflags cflags)

  Calling PKGCONFIG will fill the desired information into the 4 given arguments, e.g. PKGCONFIG(libart-2.0 LIBART_INCLUDE_DIR LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT found or the specified software package doesn't exist, the variable will be empty when the function returns, otherwise they will contain the respective information

  Defines the following macros:

         SWIG_ADD_MODULE(name language [ files ])
           - Define swig module with given name and specified language
         SWIG_LINK_LIBRARIES(name [ libraries ])
           - Link libraries to swig module

  All other macros are for internal use only. To get the actual name of the swig module, use: ${SWIG_MODULE_name_REAL_NAME}. Set Source files properties such as CPLUSPLUS and SWIG_FLAGS to specify special behavior of SWIG. Also global CMAKE_SWIG_FLAGS can be used to add special flags to all swig calls. Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the swig generated module (swig -outdir option) The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra dependencies for the generated modules.
