# Find CEGUI includes and library
#
# This module defines
#  CEGUI_INCLUDE_DIR
#  CEGUI_LIBRARY, the library to link against to use CEGUI.
#  CEGUILUA_LIBRARY, the library to link against to use the CEGUI script module.
#  CEGUI_TOLUA_LIBRARY, the library to link against to use Tolua++.
#  CEGUI_FOUND, If false, do not try to use CEGUI
#  CEGUI_VERSION, the version as string "x.y.z"
#
# Input:
#  ENV{CEGUIDIR}, CEGUI path, optional
