# Enables CD audio playback. CD audio playback is used

# dependencies. It should work on all platforms where
# CD playback is supported by SDL.
WITH_CDA:=yes

# Enables OGG/Vorbis support. OGG/Vorbis files can be
# used as a substitute of CD audio playback. Adds
# dependencies to libogg, libvorbis and libvorbisfile.

# Enables the optional OpenAL sound system.
# To use it your system needs libopenal.so.1 (we 
# recommend openal-soft) installed
WITH_OPENAL:=yes

# Enables retexturing support. Adds a dependency to
# libjpeg
WITH_RETEXTURING:=yes

# Set the gamma via X11 and not via SDL. This works
# around problems in some SDL version. Adds dependencies
# to pkg-config, libX11 and libXxf86vm. Unsupported in
# Windows.
WITH_X11GAMMA:=no

# Enables opening of ZIP files (also known as .pk3 packs).
# Adds a dependency to libz

# Enable systemwide installation of game assets
