# FindSDL_sound

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.
    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.

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.
