# - 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_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_SKIP_MARK_AS_ADVANCED - Disable marking cache variables as advanced
#
#=================
# 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 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
