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

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
This provides a linking interface that matches the one available when `find_package()` is used, by aliasing all of SDL's public targets into the SDL2:: namespace. Thus, dependees link to the same-named targets regardless of how SDL was acquired.
This approach permits the use of wrappers around CMake's FetchContent API such as https://github.com/cpm-cmake/CPM.cmake

The CMake build for SDL doesn't set SDLMAIN_SOURCES on iOS to the sources in src/main/ios. As a result, SDL fails to initialize since it falls back to the dummy main. Adding the line file(GLOB SDLMAIN_SOURCES ${SDL2_SOURCE_DIR}/src/main/uikit/*.c) fixes the issue.

stdlib: Added SDL_round, SDL_roundf, SDL_lround and SDL_lroundf
The default implementation is based on the one used in the Windows RT video driver.

Running CMake configure from a Windows Subsystem for Linux using Visual Studio Code Remote doesn't generate the header file with the current source revision, it throws "/home/sebva/SDL/build-scripts/updaterev.sh: 13: cannot create /mnt/c/Users/sebva/.vscode/extensions/ms-vscode-remote.remote-wsl-0.44.4/include/SDL_revision.h.new: Directory nonexistent".

2nd time lucky, perhaps. patch 2 applies to current HEAD at time of writing - 4eb049c9bb1ca94efe3c40b57beda3169984d0cb from https://github.com/SDL-mirror/SDL.
This basically goes back to what was there originally, but now manually adding "-x objective-c" to the clang command line rather than "-ObjC". clang is then invoked without the "-x c" that was causing the problem, the snippet builds, and Metal is detected. (I had a quick trawl through the cmake code, but I couldn't see where this is handled.)
I was moved to try this after finding SDL's own CHECK_OBJC_SOURCE_COMPILES macro, and noting what it does: 4eb049c9bb/cmake/macros.cmake (L67)
An alternative fix of course would be to use CHECK_OBJC_SOURCE_COMPILES instead of cmake's check_objc_source_compiles - but that had the same problem of getting confused by "return 0;". (Maybe that's because it's a macro? I'll defer to a cmake expert on this one.)
I decided in the end to err on the side of leaving things looking basically the same as they were before my first patch.

This is as of commit 50d804ea729accf9e3a9ce83238d0a2976a17545 from https://github.com/SDL-mirror/SDL, which is HEAD as I write (apologies, not confident with Mercurial)

mkdir build.SDL
cd build.SDL
cmake -G ../SDL/
Examine cmake output.
# Expected result
Metal is detected.
# Actual result
It appears that Metal is not detected! Note this line in the summary:
-- RENDER_METAL (Wanted: 0): OFF
# Fix
Change check_c_source_compiles to check_objc_source_compiles. The cmake script tries to add -ObjC to the clang command line, but, for whatever reason, this doesn't seem to work.
Change the test source to have an empty main. The "return 0;" line seems to confuse cmake somehow, causing it to crap out with an error about HAVE_FRAMEWORK_METAL being an unknown argument. (Maybe I'm just dense, but it's not obvious to me what the problem is here.)
With these two changes:
-- RENDER_METAL (Wanted: ON): ON
Patch attached.
This works on capability bitfields that can either come from udev or
from ioctls, so it is equally applicable to both udev and non-udev
input device detection.

- SDL_config.h.in: add missing defines SDL_SENSOR_COREMOTION
and SDL_SENSOR_WINDOWS (configure did set SDL_SENSOR_WINDOWS
but it never went in SDL_config.h or Makefile.)
- SDL_config.h.cmake: remove duplicated SDL_SENSOR_XXX cmake
defines.
- autofoo, cmake: check for sensorsapi.h header before enabling
windows sensors.
Apparently the "-x objective-c" made it down to the linker, who then treats
the .o file as Objective-C source code. Apparently the -ObjC argument does
the same thing but gets ignored by the linker.
Fixes Bugzilla #4988.

The CMake build system supports several audio frameworks for Linux: one of them is sndio.
All frameworks can be built with "runtime linking" (that is, using dlopen to load the library at runtime). In sdlchecks.cmake, there's code to do the same with sndio:
=================================================================
# Requires:
# - n/a
# Optional:
# - SNDIO_SHARED opt
# - HAVE_DLOPEN opt
macro(CheckSNDIO)
if(SNDIO)
# TODO: set include paths properly, so the sndio headers are found
check_include_file(sndio.h HAVE_SNDIO_H)
find_library(D_SNDIO_LIB sndio)
if(HAVE_SNDIO_H AND D_SNDIO_LIB)
set(HAVE_SNDIO TRUE)
file(GLOB SNDIO_SOURCES ${SDL2_SOURCE_DIR}/src/audio/sndio/*.c)
set(SOURCE_FILES ${SOURCE_FILES} ${SNDIO_SOURCES})
set(SDL_AUDIO_DRIVER_SNDIO 1)
if(SNDIO_SHARED)
if(NOT HAVE_DLOPEN)
message_warn("You must have SDL_LoadObject() support for dynamic sndio loading")
else()
FindLibraryAndSONAME("sndio")
set(SDL_AUDIO_DRIVER_SNDIO_DYNAMIC "\"${SNDIO_LIB_SONAME}\"")
set(HAVE_SNDIO_SHARED TRUE)
endif()
else()
list(APPEND EXTRA_LIBS ${D_SNDIO_LIB})
endif()
set(HAVE_SDL_AUDIO TRUE)
endif()
endif()
endmacro()
=================================================================
The feature is gated by an option called SNDIO_SHARED. It is also fully implemented in SDL_sndioaudio.c
Unfortunately, it seems there is a missing line in CMakeLists.txt, so SNDIO_SHARED is not defined:
======================================================================
set_option(ALSA "Support the ALSA audio API" ${UNIX_SYS})
dep_option(ALSA_SHARED "Dynamically load ALSA audio support" ON "ALSA" OFF)
set_option(JACK "Support the JACK audio API" ${UNIX_SYS})
dep_option(JACK_SHARED "Dynamically load JACK audio support" ON "JACK" OFF)
set_option(ESD "Support the Enlightened Sound Daemon" ${UNIX_SYS})
dep_option(ESD_SHARED "Dynamically load ESD audio support" ON "ESD" OFF)
set_option(PULSEAUDIO "Use PulseAudio" ${UNIX_SYS})
dep_option(PULSEAUDIO_SHARED "Dynamically load PulseAudio support" ON "PULSEAUDIO" OFF)
set_option(ARTS "Support the Analog Real Time Synthesizer" ${UNIX_SYS})
dep_option(ARTS_SHARED "Dynamically load aRts audio support" ON "ARTS" OFF)
set_option(NAS "Support the NAS audio API" ${UNIX_SYS})
set_option(NAS_SHARED "Dynamically load NAS audio API" ${UNIX_SYS})
set_option(SNDIO "Support the sndio audio API" ${UNIX_SYS})
set_option(FUSIONSOUND "Use FusionSound audio driver" OFF)
dep_option(FUSIONSOUND_SHARED "Dynamically load fusionsound audio support" ON "FUSIONSOUND" OFF)
======================================================================
You can see that all frameworks define a "dep_option" NAME_SHARED, and SNDIO is the only one where the option is missing.
This means that runtime loading of sndio is never activated. If sndio is found at configuration time, it is always activated in "linked" mode, so that the final binary will have a load-time dependency with libsdnio. This is unfortunate.
To fix the problem, it is sufficient to add this line:
dep_option(SNDIO_SHARED "Dynamically load the sndio audio API" ${UNIX_SYS} ON "SNDIO" OFF)
I've verified that this fixes the bug, and sndio can now be dynamically loaded as expected.

Due to the new major fcitx version is coming close, the existing code need to be ported to use new Fcitx dbus interface.
The new dbus interface is supported by both fcitx 4 and 5, and has a good side effect, which is that it will work with flatpak for free. Also the patch remove the dependency on fcitx header. Instead, it just hardcodes a few enum value in the code so need to handle the different header for fcitx4 or 5.
