This cmake is 3 years old, but it removes confusion about the CFLAGS
environment variable (as of CMake 3.10.0, reference PR #4681) and also
consolidates resolves the need to have a separate requirement for Windows
Store apps (which requires CMake 3.11.0).
CMake has standard means of setting compiler flags, such as the
-DCMAKE_C_FLAGS command line for general-purpose flags, and
-DCMAKE_BUILD_TYPE for letting it choose reasonable release/debug/etc
defaults. Trying to emulate the configure script is incorrect and confusing
here.
Fixes#1819.
Vista and later provide the SleepConditionVariableCS() function for this.
Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.
Fixes#4051.
Although GCC and Clang automatically generate color diagnostics on
terminal output, they do not do so when the compiler output is piped
through another process, like in the case for ninja-build and ccache.
Similarly, it would also be nice to be able to see the color diagnostics
on the CI build log in the web interface provided by the CI providers.
- cmake, configure (CheckDLOPEN): --enable-sdl-dlopen is now history..
detach the dl api discovery from SDL_LOADSO_DLOPEN functionality.
define HAVE_DLOPEN. also define DYNAPI_NEEDS_DLOPEN (CheckDLOPEN is
called only for relevant platforms.)
- update SDL_config.in and SDL_config.cmake accordingly.
- SDL_dynapi.h: set SDL_DYNAMIC_API to 0 if DYNAPI_NEEDS_DLOPEN is
defined, but HAVE_DLOPEN is not.
- pthread/SDL_systhread.c: conditionalize dl api use to HAVE_DLOPEN
- SDL_x11opengl.c, SDL_DirectFB_opengl.c, SDL_naclopengles.c: rely
on HAVE_DLOPEN, not SDL_LOADSO_DLOPEN.
- SDL_config_android.h, SDL_config_iphoneos.h, SDL_config_macosx.h,
SDL_config_pandora.h, and SDL_config_wiz.h: define HAVE_DLOPEN.

According to https://cmake.org/cmake/help/v3.0/module/GNUInstallDirs.html
`${CMAKE_INSTALL_LIBDIR} ` is only variable which should be used as base
directory. Without that patch on 64 bit archs libraries, cmake modules and
pkgconfig file are installed for example in /usr/lib6464 base directory.
This patch fixes#4621.

These came from HaikuPorts, specifically this patchset:
462947dd4f/media-libs/libsdl2/patches/libsdl2-2.0.14.patchset
This is just the part that is _not_ Haiku-specific. I wanted this in a
separate commit though, since I'm not really a CMake expert; if this causes
problems and we need to bisect to it, we won't be confused about it being a
Haiku issue when we get here.
Fixes#4092.
(and probably others.)
These came from HaikuPorts, specifically this patchset:
462947dd4f/media-libs/libsdl2/patches/libsdl2-2.0.14.patchset
This is just the Haiku-specific bits; the more general parts about install
dirs will be split into a different commit here.
Reference issue #4092.
When building SDL2 from git with CMake, you got libSDL2-2.0.so.1
instead of .0 (as it's the case when building with autotools).
This was caused by using LT_REVISION instead of LT_MAJOR for SOVERSION.
fixes#4310
