# - Locates the SDL_sound library
# This module depends on SDL being found and 
# must be called AFTER FindSDL.cmake is called.
#
# This module defines
# SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
# SDL_SOUND_FOUND, if false, do not try to link to SDL
# SDL_SOUND_LIBRARIES, this contains the list of libraries that you need 
# to link against. This is a read-only variable and is marked INTERNAL.
# SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
# flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
# This is available mostly for cases this module failed to anticipate for
# and you must add additional flags. This is marked as ADVANCED.
#
# This module also defines (but you shouldn't need to use directly)
# SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
# against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.
# And might define the following as needed
#  MIKMOD_LIBRARY
#  MODPLUG_LIBRARY
#  OGG_LIBRARY
#  VORBIS_LIBRARY
#  SMPEG_LIBRARY
#  FLAC_LIBRARY
#  SPEEX_LIBRARY
#
# Typically, you should not use these variables directly, and you should use
# SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other audio
# libraries (if needed) to successfully compile on your system .
#
# Created by Eric Wing. 
#
# This module is a bit more complicated than the other FindSDL* family
# modules.  The reason is that SDL_sound can be compiled in a large variety
# of different ways which are independent of platform. SDL_sound may
# dynamically link against other 3rd party libraries to get additional codec
# support, such as Ogg Vorbis, SMPEG, ModPlug, MikMod, FLAC, Speex, and
# potentially others.  Under some circumstances which I don't fully
# understand, there seems to be a requirement that dependent libraries of
# libraries you use must also be explicitly linked against in order to
# successfully compile. SDL_sound does not currently have any system in place
# to know how it was compiled.  So this CMake module does the hard work in
# trying to discover which 3rd party libraries are required for building (if
# any).
#
# This module uses a brute force approach to create a test program that uses
# SDL_sound, and then tries to build it. If the build fails, it parses the
# error output for known symbol names to figure out which libraries are
# needed.  Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable
# that would correspond to the ./configure --prefix=$SDLDIR used in building
# SDL.
#
# On OSX, this will prefer the Framework version (if found) over others.
# People will have to manually change the cache values of 
# SDL_LIBRARY to override this selection.
