# GNU Makefile for cross-compiling quakespasm.exe (Win32: MinGW)
# using cross-toolchains on a linux host, Oct. 25, 2012
# "make DEBUG=1" to build a debug client.
# "make SDL_CONFIG=/path/to/sdl-config" for unusual SDL installations.
# "make WINSOCK2=1" to use WinSock2 api instead of old WinSock 1.1.
# "make SDLNET=1" to use SDL_net (NOT recommended) instead of platform
# specific code.

### Embed custom Quakespasm console background picture
USE_QS_CONBACK=1

### Enable/disable codecs for streaming music support
USE_CODEC_WAVE=1
USE_CODEC_MP3=1
USE_CODEC_VORBIS=1

# which library to use for mp3 decoding: mad or mpg123
MP3LIB=mad
# which library to use for ogg decoding: vorbis or tremor
