# Find CEGUI includes and library
#
# This module defines
#  CEGUI_INCLUDE_DIR
#  CEGUI_LIBRARY, the library to link against to use CEGUI.
#  CEGUI_FOUND, If false, do not try to use CEGUI
#  CEGUI_VERSION, the version as string "x.y.z"
#  CEGUILUA_LIBRARY, Script module library
#  CEGUILUA_USE_INTERNAL_LIBRARY, True if CEGUILUA_LIBRARY was not defined here
#
# Input:
#  ENV{CEGUIDIR}, CEGUI path, optional
#  FIND CEGUILUA_INTERNAL_SUPPORT, List of all CEGUILua version supported
#                                  in the source repository
#  CEGUILUA_USE_EXTERNAL_LIBRARY, Force finding of CEGUILua
#
# Created by Matt Williams to find OGRE libraries
