# - Locate SDL_mixer library
# This module defines:
# SDL2_MIXER_LIBRARIES, the name of the library to link against
# SDL2_MIXER_INCLUDE_DIRS, where to find the headers
# SDL2_MIXER_FOUND, if false, do not try to link against
# SDL2_MIXER_VERSION_STRING - human-readable string containing the version of SDL_mixer
#
# For backward compatiblity the following variables are also set:
# SDLMIXER_LIBRARY (same value as SDL2_MIXER_LIBRARIES)
# SDLMIXER_INCLUDE_DIR (same value as SDL2_MIXER_INCLUDE_DIRS)
# SDLMIXER_FOUND (same value as SDL2_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).
