FindSDL_mixer

Locate SDL_mixer library

This module defines:

SDL_MIXER_LIBRARIES, the name of the library to link against
SDL_MIXER_INCLUDE_DIRS, where to find the headers
SDL_MIXER_FOUND, if false, do not try to link against
SDL_MIXER_VERSION_STRING - human-readable string containing the
                           version of SDL_mixer

For backward compatibility the following variables are also set:

SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES)
SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS)
SDLMIXER_FOUND (same value as SDL_MIXER_FOUND)

$SDLDIR is an environment variable that would correspond to the ./configure –prefix=$SDLDIR used in building SDL.

Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
