1​# - FindGTK2.cmake
2​# This module can find the GTK2 widget libraries and several of its other
3​# optional components like gtkmm, glade, and glademm.
4​#
5​# NOTE: If you intend to use version checking, CMake 2.6.2 or later is
6​# required.
7​#
8​# Specify one or more of the following components
9​# as you call this find module. See example below.
10​#
11​# gtk
12​# gtkmm
13​# glade
14​# glademm
15​#
16​# The following variables will be defined for your use
17​#
18​# GTK2_FOUND - Were all of your specified components found?
19​# GTK2_INCLUDE_DIRS - All include directories
20​# GTK2_LIBRARIES - All libraries
21​#
22​# GTK2_VERSION - The version of GTK2 found (x.y.z)
23​# GTK2_MAJOR_VERSION - The major version of GTK2
24​# GTK2_MINOR_VERSION - The minor version of GTK2
25​# GTK2_PATCH_VERSION - The patch version of GTK2
26​#
27​# Optional variables you can define prior to calling this module:
28​#
29​# GTK2_DEBUG - Enables verbose debugging of the module
30​# GTK2_SKIP_MARK_AS_ADVANCED - Disable marking cache variables as advanced
31​# GTK2_ADDITIONAL_SUFFIXES - Allows defining additional directories to
32​# search for include files
33​#
34​#=================
35​# Example Usage:
36​#
37​# Call find_package() once, here are some examples to pick from:
38​#
39​# Require GTK 2.6 or later
40​# find_package(GTK2 2.6 REQUIRED gtk)
41​#
42​# Require GTK 2.10 or later and Glade
43​# find_package(GTK2 2.10 REQUIRED gtk glade)
44​#
45​# Search for GTK/GTKMM 2.8 or later
46​# find_package(GTK2 2.8 COMPONENTS gtk gtkmm)
47​#
48​# if(GTK2_FOUND)
49​# include_directories(${GTK2_INCLUDE_DIRS})
50​# add_executable(mygui mygui.cc)
51​# target_link_libraries(mygui ${GTK2_LIBRARIES})
52​# endif()

69​# Version 1.3 (11/9/2010) (CMake 2.8.4)
70​# * 11429: Add support for detecting GTK2 built with Visual Studio 10.
71​# Thanks to Vincent Levesque for the patch.
72​
73​# Version 1.2 (8/30/2010) (CMake 2.8.3)
74​# * Merge patch for detecting gdk-pixbuf library (split off
75​# from core GTK in 2.21). Thanks to Vincent Untz for the patch
76​# and Ricardo Cruz for the heads up.
77​# Version 1.1 (8/19/2010) (CMake 2.8.3)
78​# * Add support for detecting GTK2 under macports (thanks to Gary Kramlich)
79​# Version 1.0 (8/12/2010) (CMake 2.8.3)
80​# * Add support for detecting new pangommconfig.h header file
81​# (Thanks to Sune Vuorela & the Debian Project for the patch)
82​# * Add support for detecting fontconfig.h header
83​# * Call find_package(Freetype) since it's required
84​# * Add support for allowing users to add additional library directories
85​# via the GTK2_ADDITIONAL_SUFFIXES variable (kind of a future-kludge in
86​# case the GTK developers change versions on any of the directories in the
87​# future).
88​# Version 0.8 (1/4/2010)
89​# * Get module working under MacOSX fink by adding /sw/include, /sw/lib
90​# to PATHS and the gobject library
91​# Version 0.7 (3/22/09)
92​# * Checked into CMake CVS
93​# * Added versioning support
94​# * Module now defaults to searching for GTK if COMPONENTS not specified.
95​# * Added HKCU prior to HKLM registry key and GTKMM specific environment
96​# variable as per mailing list discussion.
97​# * Added lib64 to include search path and a few other search paths where GTK
98​# may be installed on Unix systems.
99​# * Switched to lowercase CMake commands
100​# * Prefaced internal variables with _GTK2 to prevent collision
101​# * Changed internal macros to functions
102​# * Enhanced documentation
103​# Version 0.6 (1/8/08)
104​# Added GTK2_SKIP_MARK_AS_ADVANCED option
105​# Version 0.5 (12/19/08)
106​# Second release to cmake mailing list
