As with Corrade, this is not exactly backwards compatible, but for
common use case without OBJECT libraries this should not be a problem.
In any case, recreate the build dir and update your copy of all
Find*.cmake modules to avoid weird things happening.
User-facing changes:
* Documentation of all Find*.cmake modules converted to
reStructuredText to follow official CMake guidelines.
* The newfangled way to use the libraries is to link to Magnum::Shaders
instead of adding ${MAGNUM_SHADERS_INCLUDE_DIRS} to include path and
linking to ${MAGNUM_SHADERS_LIBRARIES}.
* The old ${MAGNUM_*_LIBRARIES} are deprecated and now just expand to
Magnum::* target. Use the target directly. These are also enabled
only when building with MAGNUM_BUILD_DEPRECATED.
* The old ${MAGNUM_*_INCLUDE_DIRS} are removed as the Magnum::* targets
cover these too.
Internal changes:
* Global state such as include_directories() was replaced with
target-specific settings.
Recommended fix:
https://github.com/mosra/magnum/blob/master/modules/FindSDL2.cmake#L46 to list only SDL_scancode.h (i.e. remove SDL.h)
Test:
Add SDL2 Lib to the /Libraries/Frameworks/
Builds file.
Add SDL2 Lib and SDL1 to the /Libraries/Frameworks/
Build fails.
Remove SDL.h from at line 46.
Builds fine.
Remove SDL 1 from the /Libraries/Frameworks/
Builds fine.
