-# - Locates the SDL_sound library
-#
-# This module depends on SDL being found and
-# must be called AFTER FindSDL.cmake or FindSDL2.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 or SDL2_LIBRARY to override this selection or set the CMake
-# environment CMAKE_INCLUDE_PATH to modify the search paths.
