   2 # This module finds the GTK2/GTKMM widget libraries
   3 #
   4 # Specify one or more of the following components
   5 # as you call this Find macro:
   6 #
   7 #   gtk
   8 #   gtkmm
   9 #   glade
  10 #   glademm
  11 #
  12 # The following variables will be defined for your use
  13 #   GTK2_FOUND - Were all of your specified components found?
  14 #   GTK2_INCLUDE_DIRS - All include directories
  15 #   GTK2_LIBRARIES - All libraries
  16 #
  17 # Optional variables you can define prior to calling this module
  18 #   GTK2_DEBUG - Enables verbose debugging of the module
  19 #   GTK2_SKIP_MARK_AS_ADVANCED - Disable marking cache variables as advanced
  20 #
