From 1c8bcca4ffe4b58bce9643a785d4590bc32a40a8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] cmake: drop the unused SDL2_mixer find module
cmake/sdl2/FindSDL2_mixer.cmake is left over from the SDL2 era. The
build uses find_package(SDL3_mixer) and the SDL3_mixer::SDL3_mixer
imported target, and nothing references this module (no CMAKE_MODULE_PATH
points at cmake/sdl2), so remove it.

-FindSDL2_mixer
---------------
-
-Locate SDL2_mixer library
-
-This module defines the following 'IMPORTED' target:
-
-::
-
- SDL2::Mixer
- The SDL2_mixer library, if found.
- Have SDL2::Core 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).
