# 20241024 bkw: Modified by SlackBuilds.org, BUILD=2:
# - Don't try to build with lua52 (doubleplusungood ref unbuild).
#   This thing insists on lua 5.2, but includes its own bundled
#   source, which it will build if -DUSE_SYSTEM_LIBLUA=OFF. I assume
#   the game was actually tested with the bundled lua, so let's use it.
#   Thought about doing the same with the bundled glew, but glew looks
#   like it might depend a lot on the mesa version in use, so I left
#   it alone (keep using the system one).
