# - 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_sound
# 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.
# SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound
#
# 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 selectionor set the CMake environment
# CMAKE_INCLUDE_PATH to modify the search paths.

# CMake is giving me problems using TRY_COMPILE with the CMAKE_FLAGS
# for the :STRING syntax if I have multiple values contained in a
# single variable. This is a problem for the SDL_LIBRARY variable
# because it does just that. When I feed this variable to the command,
# only the first value gets the appropriate modifier (e.g. -I) and
# the rest get dropped.
# To get multiple single variables to work, I must separate them with a "\;"
# I could go back and modify the FindSDL.cmake module, but that's kind of painful.
# The solution would be to try something like:
# set(SDL_TRY_COMPILE_LIBRARY_LIST "${SDL_TRY_COMPILE_LIBRARY_LIST}\;${CMAKE_THREAD_LIBS_INIT}")
# Instead, it was suggested on the mailing list to write a temporary CMakeLists.txt
