# - FindGTK3.cmake
# This module can find the GTK3 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
#
#   GTK3_FOUND - Were all of your specified components found?
#   GTK3_INCLUDE_DIRS - All include directories
#   GTK3_LIBRARIES - All libraries
#
#   GTK3_VERSION - The version of GTK3 found (x.y.z)
#   GTK3_MAJOR_VERSION - The major version of GTK3
#   GTK3_MINOR_VERSION - The minor version of GTK3
#   GTK3_PATCH_VERSION - The patch version of GTK3
#
# Optional variables you can define prior to calling this module:
#
#   GTK3_DEBUG - Enables verbose debugging of the module
#   GTK3_SKIP_MARK_AS_ADVANCED - Disable marking cache variables as advanced
#   GTK3_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 3.0 or later
#       find_package(GTK3 3.0 REQUIRED gtk)
#
#   if(GTK3_FOUND)
#      include_directories(${GTK3_INCLUDE_DIRS})
#      add_executable(mygui mygui.cc)
#      target_link_libraries(mygui ${GTK3_LIBRARIES})
#   endif()
