Yet again I merged too soon :/ b70ac5fa51
was not working for me at all -- on Arch the installed config file has
only one IMPORTED_CONFIGURATION, NOCONFIG, which wasn't propagated.
Besides that, there were some compiler definitions and other things that
*also* weren't propagated from the config file.
Reworked it totally in a simpler way, which doesn't work on CMake 2.8.12
anymore (but also who cares, systems that are stuck on 2.8.12 don't have
GLFW3 in repositories anyway).
It's not like with SDL where we can't use <SDL2/SDL.h> due to macOS
packaged shipped without the SDL2 include directory.
This was just a bad copypaste from the FindSDL2.cmake module, probably.
This affect virtually *all* targets so I would need to put this
everywhere, which I'm not. I am putting this only for the most often
used (and thus most problematic) dependencies, which is SDL and GLFW.
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.
It's meaningless to have *_INCLUDE_DIR point to the dir where
{egl.h,gl2.h,gl3.h} exists, because we're always including the files
using full path (e.g. <EGL/egl.h>). It then fails miserably at compile
time on platforms which don't have the parent directory in include path.
