While the CMake build checks for ibus and does enable the ibus backend with set(HAVE_IBUS_IBUS_H TRUE), this does not define SDL_USE_IME, thus CMake built SDL2 (as in Arch Linux) cannot use IME at all.
The attached patch fixes this behaviour when building against ibus. IME support will still fail when only fcitx is available on the build system.
This is currently supported on Linux and macOS. iOS and Android are not
supported at all, Windows support could be added with some changes to the libusb
backend. The Visual Studio and Xcode projects do not use this feature.
Based on Valve Software's hid.cpp, written in collaboration with Andrew Eikum.
(and it defaults to "yes" on those platforms. Other places, which use libusb,
still default to no because they probably need root permissions to work.)

A horde of strict aliasing violation warnings are emitted from joystick
layer, and also from a few other places. This happens with gcc-4.4.7 on
Linux CentOS 6.10. Some other sysjoystick would possibly have the same
warnings.
Attached my full log here. Example entry:
src/joystick/SDL_joystick.c: In function 'SDL_GetJoystickGUIDInfo':
src/joystick/SDL_joystick.c:1094: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules

The evdev interface is available on FreeBSD, with the xf86-input-evdev for include files in /usr/local/include/linux, so <linux/input.h> works, or when build with the native evdev option, where <dev/evdev/input.h> is available.
This lets you build a custom embedded device that roughly offers the "this
process is going to the background NOW" semantics of SDL on a mobile device.

I am having a parallel build problem with -j3 or higher using the autotools build and slibtool instead of GNU libtool. Basically slibtool is faster than GNU libtool and it will start working before mkdir starts or finishes creating the build/ directory.
From Tom Black:
I'm having problems initializing the sensor module. I'm compiling with a standard ./configure && make && sudo make install, and the module says it's enabled, but SDL_Init(SDL_INIT_EVERYTHING) is failing with SDL_GetError() returning "SDL not built with sensor support".
add HAVE_ENDPOINTVOLUME_H, HAVE_MMDEVICEAPI_H and HAVE_AUDIOCLIENT_H
in SDL_config.h.in, SDL_config.h.cmake, SDL_config_windows.h, and in
SDL_config_winrt.h.
Now you don't need the latest Wayland installed to build with
newer protocols supported, as they'll build correctly; even if
your system can't use them, we can make intelligent decisions
at runtime about what's available on the current machine anyhow.
This also simplifies some logic and possible failure cases in
the configure and CMake scripts.
Fixes Bugzilla #4207.
This is just in parity with the existing zxdg-shell-unstable-v6 code. Making
the Wayland target robust (and uh, with title bars) is going to take a lot
of work on top of this.

Running top-level SDL configure on macOS 10.11 resulted in the errors below because automake removed the brackets about the tests.
./configure: line 15756: : command not found
./configure: line 15759: -Iinclude -I/Users/zack/SDL/include -idirafter /Users/zack/SDL/src/video/khronos : No such file or directory
./configure: line 15763: : command not found

When you try use SDL2 2.0.8 in CMake project in Linux, it complains about trailing spaces in sdl2.pc:
CMake Error at CMakeLists.txt:147 (add_executable):
Target "TestSimpleMain" links to item "-L/usr/lib64 -lSDL2 " which has
leading or trailing whitespace. This is now an error according to policy
CMP0004.

Configury adds Metal.framework to linkage even if it is not available.
My solution is setting enable_render_metal to no when Metal.framework
is not found
