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).
