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.
