+FindGTK2
+--------
+
+Find the GTK2 widget libraries and several of its other optional components
+like ``gtkmm``, ``glade``, and ``glademm``.
+
+Specify one or more of the following components as you call this find
+module.  See example below.
+
+* ``gtk``
+* ``gtkmm``
+* ``glade``
+* ``glademm``
+
+Result Variables
+^^^^^^^^^^^^^^^^
+
+The following variables will be defined for your use
+
+``GTK2_FOUND``
+  Were all of your specified components found?
+``GTK2_INCLUDE_DIRS``
+  All include directories
+``GTK2_LIBRARIES``
+  All libraries
+``GTK2_TARGETS``
+  All imported targets
+``GTK2_DEFINITIONS``
+  Additional compiler flags
+``GTK2_VERSION``
+  The version of GTK2 found (x.y.z)
+``GTK2_MAJOR_VERSION``
+  The major version of GTK2
+``GTK2_MINOR_VERSION``
+  The minor version of GTK2
+``GTK2_PATCH_VERSION``
+  The patch version of GTK2
+
+Input Variables
+^^^^^^^^^^^^^^^
+
+Optional variables you can define prior to calling this module:
+
+``GTK2_DEBUG``
+  Enables verbose debugging of the module
+``GTK2_ADDITIONAL_SUFFIXES``
+  Allows defining additional directories to search for include files
+
+Example Usage
+^^^^^^^^^^^^^
+
+Call :command:`find_package` once.  Here are some examples to pick from:
+
+Require GTK 2.6 or later:
+
+.. code-block:: cmake
+
+  find_package(GTK2 2.6 REQUIRED gtk)
+
+Require GTK 2.10 or later and Glade:
+
+.. code-block:: cmake
+
+  find_package(GTK2 2.10 REQUIRED gtk glade)
+
+Search for GTK/GTKMM 2.8 or later:
+
+.. code-block:: cmake
+
+  find_package(GTK2 2.8 COMPONENTS gtk gtkmm)
+
+Use the results:
+
+.. code-block:: cmake
+
+  if(GTK2_FOUND)
+    include_directories(${GTK2_INCLUDE_DIRS})
+    add_executable(mygui mygui.cc)
+    target_link_libraries(mygui ${GTK2_LIBRARIES})
+  endif()
+#]=======================================================================]
+
+# Version 1.6 (CMake 3.0)
+#   * Create targets for each library
+#   * Do not link libfreetype
+# Version 1.5 (CMake 2.8.12)
+#   * 14236: Detect gthread library
+#            Detect pangocairo on windows
+#            Detect pangocairo with gtk module instead of with gtkmm
+#   * 14259: Use vc100 libraries with VS 11
+#   * 14260: Export a GTK2_DEFINITIONS variable to set /vd2 when appropriate
+#            (i.e. MSVC)
+#   * Use the optimized/debug syntax for _LIBRARY and _LIBRARIES variables when
+#     appropriate. A new set of _RELEASE variables was also added.
+#   * Remove GTK2_SKIP_MARK_AS_ADVANCED option, as now the variables are
+#     marked as advanced by SelectLibraryConfigurations
+#   * Detect gmodule, pangoft2 and pangoxft libraries
+# Version 1.4 (10/4/2012) (CMake 2.8.10)
+#   * 12596: Missing paths for FindGTK2 on NetBSD
+#   * 12049: Fixed detection of GTK include files in the lib folder on
+#            multiarch systems.
+# Version 1.3 (11/9/2010) (CMake 2.8.4)
+#   * 11429: Add support for detecting GTK2 built with Visual Studio 10.
+#            Thanks to Vincent Levesque for the patch.
+# Version 1.2 (8/30/2010) (CMake 2.8.3)
+#   * Merge patch for detecting gdk-pixbuf library (split off
+#     from core GTK in 2.21).  Thanks to Vincent Untz for the patch
+#     and Ricardo Cruz for the heads up.
+# Version 1.1 (8/19/2010) (CMake 2.8.3)
+#   * Add support for detecting GTK2 under macports (thanks to Gary Kramlich)
+# Version 1.0 (8/12/2010) (CMake 2.8.3)
+#   * Add support for detecting new pangommconfig.h header file
+#     (Thanks to Sune Vuorela & the Debian Project for the patch)
+#   * Add support for detecting fontconfig.h header
+#   * Call find_package(Freetype) since it's required
+#   * Add support for allowing users to add additional library directories
+#     via the GTK2_ADDITIONAL_SUFFIXES variable (kind of a future-kludge in
+#     case the GTK developers change versions on any of the directories in the
+#     future).
+# Version 0.8 (1/4/2010)
+#   * Get module working under MacOSX fink by adding /sw/include, /sw/lib
+#     to PATHS and the gobject library
+# Version 0.7 (3/22/09)
+#   * Checked into CMake CVS
+#   * Added versioning support
+#   * Module now defaults to searching for GTK if COMPONENTS not specified.
+#   * Added HKCU prior to HKLM registry key and GTKMM specific environment
+#      variable as per mailing list discussion.
+#   * Added lib64 to include search path and a few other search paths where GTK
+#      may be installed on Unix systems.
+#   * Switched to lowercase CMake commands
+#   * Prefaced internal variables with _GTK2 to prevent collision
+#   * Changed internal macros to functions
+#   * Enhanced documentation
+# Version 0.6 (1/8/08)
+#   Added GTK2_SKIP_MARK_AS_ADVANCED option
+# Version 0.5 (12/19/08)
+#   Second release to cmake mailing list

+FindPackageHandleStandardArgs
+-----------------------------
+
+This module provides a function intended to be used in :ref:`Find Modules`
+implementing :command:`find_package(<PackageName>)` calls.  It handles the
+``REQUIRED``, ``QUIET`` and version-related arguments of ``find_package``.
+It also sets the ``<PackageName>_FOUND`` variable.  The package is
+considered found if all variables listed contain valid results, e.g.
+valid filepaths.
+
+.. command:: find_package_handle_standard_args
+
+  There are two signatures::
+
+    find_package_handle_standard_args(<PackageName>
+      (DEFAULT_MSG|<custom-failure-message>)
+      <required-var>...
+      )
+
+    find_package_handle_standard_args(<PackageName>
+      [FOUND_VAR <result-var>]
+      [REQUIRED_VARS <required-var>...]
+      [VERSION_VAR <version-var>]
+      [HANDLE_COMPONENTS]
+      [CONFIG_MODE]
+      [NAME_MISMATCHED]
+      [REASON_FAILURE_MESSAGE <reason-failure-message>]
+      [FAIL_MESSAGE <custom-failure-message>]
+      )
+
+  The ``<PackageName>_FOUND`` variable will be set to ``TRUE`` if all
+  the variables ``<required-var>...`` are valid and any optional
+  constraints are satisfied, and ``FALSE`` otherwise.  A success or
+  failure message may be displayed based on the results and on
+  whether the ``REQUIRED`` and/or ``QUIET`` option was given to
+  the :command:`find_package` call.
+
+  The options are:
+
+  ``(DEFAULT_MSG|<custom-failure-message>)``
+    In the simple signature this specifies the failure message.
+    Use ``DEFAULT_MSG`` to ask for a default message to be computed
+    (recommended).  Not valid in the full signature.
+
+  ``FOUND_VAR <result-var>``
+    Obsolete.  Specifies either ``<PackageName>_FOUND`` or
+    ``<PACKAGENAME>_FOUND`` as the result variable.  This exists only
+    for compatibility with older versions of CMake and is now ignored.
+    Result variables of both names are always set for compatibility.
+
+  ``REQUIRED_VARS <required-var>...``
+    Specify the variables which are required for this package.
+    These may be named in the generated failure message asking the
+    user to set the missing variable values.  Therefore these should
+    typically be cache entries such as ``FOO_LIBRARY`` and not output
+    variables like ``FOO_LIBRARIES``. This option is mandatory if
+    ``HANDLE_COMPONENTS`` is not specified.
+
+  ``VERSION_VAR <version-var>``
+    Specify the name of a variable that holds the version of the package
+    that has been found.  This version will be checked against the
+    (potentially) specified required version given to the
+    :command:`find_package` call, including its ``EXACT`` option.
+    The default messages include information about the required
+    version and the version which has been actually found, both
+    if the version is ok or not.
+
+  ``HANDLE_COMPONENTS``
+    Enable handling of package components.  In this case, the command
+    will report which components have been found and which are missing,
+    and the ``<PackageName>_FOUND`` variable will be set to ``FALSE``
+    if any of the required components (i.e. not the ones listed after
+    the ``OPTIONAL_COMPONENTS`` option of :command:`find_package`) are
+    missing.
+
+  ``CONFIG_MODE``
+    Specify that the calling find module is a wrapper around a
+    call to ``find_package(<PackageName> NO_MODULE)``.  This implies
+    a ``VERSION_VAR`` value of ``<PackageName>_VERSION``.  The command
+    will automatically check whether the package configuration file
+    was found.
+
+  ``REASON_FAILURE_MESSAGE <reason-failure-message>``
+    Specify a custom message of the reason for the failure which will be
+    appended to the default generated message.
+
+  ``FAIL_MESSAGE <custom-failure-message>``
+    Specify a custom failure message instead of using the default
+    generated message.  Not recommended.
+
+  ``NAME_MISMATCHED``
+    Indicate that the ``<PackageName>`` does not match
+    ``${CMAKE_FIND_PACKAGE_NAME}``. This is usually a mistake and raises a
+    warning, but it may be intentional for usage of the command for components
+    of a larger package.
+
+Example for the simple signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibXml2 DEFAULT_MSG
+    LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
+
+The ``LibXml2`` package is considered to be found if both
+``LIBXML2_LIBRARY`` 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 a
+:command:`message(FATAL_ERROR)`, independent whether ``QUIET`` was
+used or not.  If it is found, success will be reported, including
+the content of the first ``<required-var>``.  On repeated CMake runs,
+the same message will not be printed again.
+
+.. note::
+
+  If ``<PackageName>`` does not match ``CMAKE_FIND_PACKAGE_NAME`` for the
+  calling module, a warning that there is a mismatch is given. The
+  ``FPHSA_NAME_MISMATCHED`` variable may be set to bypass the warning if using
+  the old signature and the ``NAME_MISMATCHED`` argument using the new
+  signature. To avoid forcing the caller to require newer versions of CMake for
+  usage, the variable's value will be used if defined when the
+  ``NAME_MISMATCHED`` argument is not passed for the new signature (but using
+  both is an error)..
+
+Example for the full signature:
+
+.. code-block:: cmake
+
+  find_package_handle_standard_args(LibArchive
+    REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR
+    VERSION_VAR LibArchive_VERSION)
+
+In this case, the ``LibArchive`` package is considered to be found if
+both ``LibArchive_LIBRARY`` and ``LibArchive_INCLUDE_DIR`` are valid.
+Also the version of ``LibArchive`` will be checked by using the version
+contained in ``LibArchive_VERSION``.  Since no ``FAIL_MESSAGE`` is given,
+the default messages will be printed.
+
+Another example for the full signature:
+
+.. code-block:: cmake
+
+  find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
+  find_package_handle_standard_args(Automoc4  CONFIG_MODE)
+
+In this case, a ``FindAutmoc4.cmake`` module wraps a call to
+``find_package(Automoc4 NO_MODULE)`` and adds an additional search
+directory for ``automoc4``.  Then the call to
+``find_package_handle_standard_args`` produces a proper success/failure
+message.

+FindPackageMessage
+------------------
+
+.. code-block:: cmake
+
+  find_package_message(<name> "message for user" "find result details")
+
+This function 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:
+
+.. code-block:: cmake
+
+  if(X11_FOUND)
+    find_package_message(X11 "Found X11: ${X11_X11_LIB}"
+      "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
+  else()
+   ...
+  endif()
+#]=======================================================================]
+

+  if(NOT ${pkg}_FIND_QUIETLY)

+      # message again.

+to ``basename_LIBRARY_DEBUG-NOTFOUND``.  If only ``basename_LIBRARY_DEBUG``
+is defined, then ``basename_LIBRARY`` will take the debug value, and
+``basename_LIBRARY_RELEASE`` will be set to ``basename_LIBRARY_RELEASE-NOTFOUND``.
+
+If the generator supports configuration types, then ``basename_LIBRARY``
+and ``basename_LIBRARIES`` will be set with debug and optimized flags
+specifying the library to be used for the given configuration.  If no
+build type has been set or the generator in use does not support
