# 20230110 bkw: modified by SlackBuilds.org, BUILD=5.
# - Install to /opt/CEGUI0.7, not /usr. Resolves the conflict with
#   CEGUI. Apps that depend on this will have to be modified to
#   use /opt/CEGUI0.7 (only games/smc depends on this, though).
# - Disable irrlicht renderer (unneeded).
# - Disable ogre renderer (fails to build with modern ogre).
# - Add FreeImage to REQUIRES. Our one dependee (smc) requires
#   a CEGUI0.7 that was built with FreeImage support.
