Such as telling people Sdl2Application is not available on Android, or
that EmscriptenApplication needs WITH_EMSCRIPTENAPPLICATION enabled in
order to be built and installed.
With blackjack and actually working properly on all platforms.
Seriously, did nobody ever try to use the vanilla version on Mac or MSYS
since it was added several years ago in CMake 3.7?
Basically using the same idea as with the discrete version -- having the
second dimension dynamic, together with restricting the implementation to
just Float and Double.
According to the SubdivideRemoveDuplicatesBenchmark, this makes the
implementation slightly slower. I presume this is due to how minmax and
offsets are calculated which is quite cache-inefficient as it goes over
the same memory block multiple times. Added a TODO for later.
Same as in Corrade. Because BUILD_STATIC is independent between Corrade
and Magnum this option is also independent -- the corner cases and bad
interactions would be otherwise too complex to handle (e.g., in case of
a dynamic Corrade and static Magnum it would be impossible to enable
this option for Magnum etc etc).
Should not have any functional change, however we can now use the
imported target (instead of a variable that can be empty if threads
are not found), using REQUIRED because otherwise it makes no sense, and
checking explicitly for both libraries instead of the merged variable
(because there it's only an accident it actually works).
Don't try to look for them if we don't use them. It only makes people
install additional outdated crap on their machines for no reason. The
only case where platform-specific GL headers are needed is in case of
iOS which doesn't provide any means of function pointer loading, but
there the include is passed implicitly from the framework.
Emscripten's MINIMAL_RUNTIME requires -lGL or -lopenal to be specified
(the default does that implicitly). It doesn't hurt to do that every
time and it makes the Find modules slightly simpler.
If building with deprecated features enabled, the buildsystem checks if
the option is still set and is inconsistent with what Corrade reports
and reports a deprecation warning. For backwards compatibility the
MAGNUM_BUILD_MULTITHREADED CMake variable and preprocessor macro are
still provided as well.
