# bsd.sdl.mk - Support for SDL-based ports.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# For FreeBSD committers:
# - Changes in the version number of the shared libraries are encouraged.
# - For the rest, please try to run them via the maintainer but feel free
#   to commit themselves if nothing breaks.
#
# For ports-developers:
# If your port needs SDL or one of the SDL modules, you can easily
# include them with the "USE_SDL=" statement. For example if you need
# the standard SDL and SDL_sound, use "USE_SDL=sdl sound" and the
# required libraries are included in your LIB_DEPENDS.
#
# If you want to check for the availability for certain SDL ports, you
# can set WANT_SDL and run it through bsd.port.pre.mk:
#	WANT_SDL=	yes
#	USE_SDL=	sdl
#	.include <bsd.port.pre.mk>
#	.if ${HAVE_SDL:Mgraphics}
#	USE_SDL+=	graphics
#	.endif
#	.include <bsd.port.post.mk>
# Run "make -V USE_SDL" to see which libs are asked for at the end.
