| # 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 selectionor set the CMake environment |
| # CMAKE_INCLUDE_PATH to modify the search paths. |
