# Enables CD audio playback. CD audio playback is used
# for the background music and doesn't add any further
# 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.
WITH_OGG:=yes

# Enables the optional OpenAL sound system.
# To use it your system needs libopenal.so.1
# or openal32.dll (we recommend openal-soft)
# installed
WITH_OPENAL:=yes

# Enables optional runtime loading of OpenAL (dlopen or
# similar). If set to "no", the library is linked in at
# compile time in the normal way. On Windows this option
# is ignored, OpenAL is always loaded at runtime.
DLOPEN_OPENAL:=yes

# Use SDL2 instead of SDL1.2. Disables CD audio support,
# because SDL2 has none. Use OGG/Vorbis music instead :-)
# On Windows sdl-config isn't used, so make sure that
# you've got the SDL2 headers and libs installed.
WITH_SDL2:=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 on
# Windows and OS X.
WITH_X11GAMMA:=no

# Enables opening of ZIP files (also known as .pk3 paks).
# Adds a dependency to libz
WITH_ZIP:=yes

# Enable systemwide installation of game assets
WITH_SYSTEMWIDE:=no

# This will set the default SYSTEMDIR, a non-empty string
# would actually be used. On Windows normals slashes (/)
# instead of backslashed (\) should be used! The string
# MUST NOT be surrounded by quotation marks!
WITH_SYSTEMDIR:=""

# This will set the architectures of the OSX-binaries.
# You have to make sure your libs/frameworks supports
# these architectures! To build an universal ppc-compatible
# one would add -arch ppc for example.
OSX_ARCH:=-arch $(shell uname -m | sed -e s/i.86/i386/)
