Raw Blame History

# - FindGTK2.cmake
# This module can find the GTK2 widget libraries and several of its other
# optional components like gtkmm, glade, and glademm.
#
# NOTE: If you intend to use version checking, CMake 2.6.2 or later is
# required.
#
# Specify one or more of the following components
# as you call this find module. See example below.
#
# gtk
# gtkmm
# glade
# glademm
#
# 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_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
#
# 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 find_package() once, here are some examples to pick from:
#
# Require GTK 2.6 or later
# find_package(GTK2 2.6 REQUIRED gtk)
#
# Require GTK 2.10 or later and Glade
# find_package(GTK2 2.10 REQUIRED gtk glade)
#
# Search for GTK/GTKMM 2.8 or later
# find_package(GTK2 2.8 COMPONENTS gtk gtkmm)
#
# if(GTK2_FOUND)
# include_directories(${GTK2_INCLUDE_DIRS})
# add_executable(mygui mygui.cc)
# target_link_libraries(mygui ${GTK2_LIBRARIES})
# endif()

# Version 1.5 (UNRELEASED) (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 MSVC11
# * 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
