# FindSDL2_mixer
|
|
# -------------
|
|
#
|
|
# Locate SDL2_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 SDL2_mixer
|
|
#
|
|
#
|
|
#
|
|
# For backward compatiblity the following variables are also set:
|
|
#
|
|
# ::
|
|
#
|
|
# SDL2MIXER_LIBRARY (same value as SDL2_MIXER_LIBRARIES)
|
|
# SDL2MIXER_INCLUDE_DIR (same value as SDL2_MIXER_INCLUDE_DIRS)
|
|
# SDL2MIXER_FOUND (same value as SDL2_MIXER_FOUND)
|
|
#
|
|
#
|
|
#
|
|
# $SDL2DIR is an environment variable that would correspond to the
|
|
# ./configure --prefix=$SDL2DIR used in building SDL2.
|
|
#
|
|
# Created by Andreas Löf. This was influenced by the FindSDL_mixer.cmake
|
|
# module, but with modifications to use SDL2.
