- FindSDL2_mixer
- --------------
- Locate SDL2_mixer library
- This module defines the following 'IMPORTED' target:
- ::
- SDL2::Mixer
- The SDL2_mixer library, if found.
- Have SDL2::SDL2 as a link dependency.
- This module will set the following variables in your project:
- ::
- 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
- This module responds to the following cache variables:
- ::
- SDL2_MIXER_PATH
- Set a custom SDL2_mixer Library path (default: empty)
- SDL2_MIXER_NO_DEFAULT_PATH
- Disable search SDL2_mixer Library in default path.
- If SDL2_MIXER_PATH (default: ON)
- Else (default: OFF)
- SDL2_MIXER_INCLUDE_DIR
- SDL2_mixer headers path.
- SDL2_MIXER_LIBRARY
- SDL2_mixer Library (.dll, .so, .a, etc) path.
- Additional Note: If you see an empty SDL2_MIXER_LIBRARY in your project
- configuration, it means CMake did not find your SDL2_mixer library
- (SDL2_mixer.dll, libsdl2_mixer.so, etc). Set SDL2_MIXER_LIBRARY to point
- to your SDL2_mixer library, and configure again. This value is used to
- generate the final SDL2_MIXER_LIBRARIES variable and the SDL2::Mixer target,
- but when this value is unset, SDL2_MIXER_LIBRARIES and SDL2::Mixer does not
- get created.
- $SDL2MIXERDIR is an environment variable that would correspond to the
- ./configure --prefix=$SDL2MIXERDIR used in building SDL2_mixer.
- $SDL2DIR is an environment variable that would correspond to the
- ./configure --prefix=$SDL2DIR used in building SDL2.
- Created by Amine Ben Hassouna:
- Adapt FindSDL_mixer.cmake to SDL2_mixer (FindSDL2_mixer.cmake).
- Add cache variables for more flexibility:
- SDL2_MIXER_PATH, SDL2_MIXER_NO_DEFAULT_PATH (for details, see doc above).
- Add SDL2 as a required dependency.
- Modernize the FindSDL2_mixer.cmake module by creating a specific target:
- SDL2::Mixer (for details, see doc above).
- Original FindSDL_mixer.cmake module:
- 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).
