check_include_path is not meant to be used to check for presence of a
library. This is because a BOOL is cached.
Avoid this caching by using find_file.
`find_file` caches a patch instead of a bool and will always run when
the result failed.
Modern CMake doesn't need "LANGUAGE C" for Objective-C
set_source_files_properties(${COCOA_SOURCES} PROPERTIES LANGUAGE C) should be removed fro video/cocoa/*.m as well otherwise project won't compile

If egl.pc sets at least two macros as the i.MX Vivante driver does, e.g.:
| Cflags: -I${includedir} -DLINUX -DWL_EGL_PLATFORM
then we get the following error during configuration:
| -- Performing Test HAVE_OPENGL_EGL
| CMake Error: Parse error in command line argument: WL_EGL_PLATFORM
| Should be: VAR:type=value
If one changes to add a value to the macro, e.g.
| Cflags: -I${includedir} -DLINUX=1 -DWL_EGL_PLATFORM=1
then cmake does not error out but the macro is not passed to the
C compiler.
CMAKE_REQUIRED_FLAGS is the wrong variable to pass the CFLAGS in,
CMAKE_REQUIRED_DEFINITIONS should be used.

- SDL_CLOCK_GETTIME now defaults to ON to match autotools build
- Add detection of float.h and Xdbe
- Fix detection of pthread_setname_np() (requires _GNU_SOURCE)
- Move SDL_USE_IME definition into SDL_config.h.cmake
This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.
We don't use it, it was a leftover from 1.2, I think, and it doesn't exist
on Solaris, so this should hopefully fix the build there.
This also means we don't need the configure/cmake checks for
SDL_VIDEO_DRIVER_X11_CONST_PARAM_XEXTADDDISPLAY, so that was removed also.
Fixes#1666.
The wrong logic, copy/pasted to a bunch of places, would correctly disable
the dynamic loading but fail to specify the libraries that SDL would now need
to explicitly link against.
- 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.
