# - Find GD
# Find the native GD includes and library
# This module defines
# GD_INCLUDE_DIR, where to find gd.h, etc.
# GD_LIBRARIES, the libraries needed to use GD.
# GD_FOUND, If false, do not try to use GD.
# also defined, but not for general use are
# GD_LIBRARY, where to find the GD library.
# GD_SUPPORTS_PNG, GD_SUPPORTS_JPEG, GD_SUPPORTS_GIF, test
# support for image formats in GD.
