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.)

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.
Wayland video subsystem uses a mix of libc and SDL function.
This patch switches libc functions to SDL ones and fixes a mismatch in memory
allocation/dealoccation of SDL_Cursor in SDL_waylandmouse.c (calloc on line 201
and SDL_free on line 313) which caused memory corruption if custom memory
allocator where provided to SDL.
As written, these contain undefined stack contents, which in practice
causes crashes/hangs and/or triggers the validation layers (they
complain about `pNext` and `flags` not being NULL).
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
The GCC-style SDL2_LIBRARIES were lacking the rpath on Linux, which
seems to be implicitly set when linking path/to/libSDL2-2.0.so.0.*
and is explicitly set in the SDL2_LIBRARIES in sdl2-config.cmake
(from some autotools variable), so I removed that hack and the format
remains sth like "path/to/libSDL2main.a;path/to/libSDL2-2.0.so.0.14.1".
It's still in the revision history in case it turns out that some
platform really needs the "-L/path/to/bla/lib -lSDL2main -lSDL2" format
It didn't work at all because shared libs defined in CMake with
add_library() need something like IMPORTED_IMPLIB (pointing to a .dll.a
or .lib for th DLLs) set to link on Windows.
But even with that it didn't work because the order of the libs is very
important: it must be -lmingw32 -lSDL2main -lSDL -mwindows - but
with normal add_library(SDL2::SDL2 SHARED IMPORTED) libs, SDL2 itself
is always linked first.
So I use an "INTERFACE" library (usually used for header-only libs), which
doesn't implicitly/automatically link anything so I can specify the whole
order of the linked libs.
(SDL2::SDL2-static is completely untested)
