Respect the BUILD_SHARED_LIBS variable when defined, and build either shared or static libs, which is CMake's default behavior (See https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html).
If the variable is not defined, the current behavior remains unchanged and both variants are built where the platform supports it. This way, it remains possible to build both in one shot, which seems convenient for distro builds and useful to promote some consistency between them.

Followup to #3651
As already noted by Ryan, no framework is being built, so we better install to lib/cmake.
That code was originally part of a patch submitted by David Demelier, whose credit BTW got lost (I combined his patch for #3572 with fixes for #2576 and #3613 resulting in #3651 because things started to depend on another).
I tested that the configuration files are found correctly in the new location on MacOS X based on a hint to the root (see https://cmake.org/cmake/help/latest/command/find_package.html#search-procedure).

I noticed that the current Android.mk builds a libhidapi.so library for Android but the CMake build hasn't been updated to do so. I'll attach a patch that fixes this issue.
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.
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".

CMake: fix building tests on Linux
In case where libunwind.h has been found, it will be used by compiler,
but linker wasn't updated to reflect use of this new library.
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.

After attempting to use SDL2 in the way described in this bug, I found the main issue was the includes not being added to the compiler command.
I found the issue was that the target_include_directories commands for the SDL2, SDL2-static and SDL2main targets only sets the public includes for installations using the INSTALL_INTERFACE generator expression.
I have written a patch to CMakeLists.txt that fixes this issue by adding another item to the target_include_directories commands, utilizing the BUILD_INTERFACE generator expression to correctly add the include directory during builds.
Previously the include path was {INSTALL_PREFIX}/include,
it is now {INSTALL_PREFIX}/include/SDL2 to be consistent with
the other build and package configuration systems.
Fixes#4128.

Patch to support building the tests with cmake.
Disabled by default, use: "cmake .. -DSDL_TEST=YES" to enable the tests.
Tested on macOS 10.13 with the ninja, makefile, and Xcode generators, and Windows 10 with the Visual Studio 2017 generator.
XAudio2 doesn't have capture support, so WASAPI was to replace it; the holdout
was WinRT, which still needed it as its primary audio target until the WASAPI
code code be made to work.
The support matrix now looks like:
WinXP: directsound by default, winmm as a fallback for buggy drivers.
Vista+: WASAPI (directsound and winmm as fallbacks for debugging).
WinRT: WASAPI

Seems latest google angle library successfully built & tested under macOS'es.

We need to use GLES2 to implement true cross-platform code.

There is a typo in CMakeLists.txt that makes CMake exit with failure.
Change that causes the problem: (Notice the double ending brackets)
${SDL2_SOURCE_DIR}/src/video/*.c)
+ ${SDL2_SOURCE_DIR}/src/video/yuv2rgb/*.c)
Fix:
Just remove the first ending bracket resulting in:
${SDL2_SOURCE_DIR}/src/video/*.c
${SDL2_SOURCE_DIR}/src/video/yuv2rgb/*.c)
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

In my cross-build environment with cmake-2.8.12.1, cmake does not add
SDL_coreaudio.m to its makefiles and the result is a failure. The fix
is simple: set the language to C for it as it is done at other places
in CMakeLists.txt.

In my project, the 'uninstall' target is already created by the glew library. I get this error when SDL2 tries to create it:
CMake Error at _build/3rdparty/SDL2/SDL2-2.0.6/CMakeLists.txt:1816 (add_custom_target):
add_custom_target cannot create target "uninstall" because another target
with the same name already exists. The existing target is a custom target
created in source directory
"D:/Code/sdl2-tutorial/_build/3rdparty/glew/glew-2.1.0/build/cmake". See
documentation for policy CMP0002 for more details.
To fix it, go to the bottom of the SDL2 CMakeLists.txt file. Add an if statement to check for the existence of the target before creating it. The end result looks like this:
if(NOT TARGET uninstall)
configure_file(
"${CMAKE_CURRENT_SOURCE_DIR}/cmake_uninstall.cmake.in"
"${CMAKE_CURRENT_BINARY_DIR}/cmake_uninstall.cmake"
IMMEDIATE @ONLY)
add_custom_target(uninstall
COMMAND ${CMAKE_COMMAND} -P ${CMAKE_CURRENT_BINARY_DIR}/cmake_uninstall.cmake)
endif()
This is how the glew library deals with this possibility in their CMakeLists.txt file.

In my existing CMake project, I use add_subdirectory to add the source for SDL2. This worked fine in 2.0.5, but now in 2.0.6 when I build the INSTALL CMake target, I get this error:
file INSTALL cannot find "D:/path/to/SDL2Config.cmake".
Call Stack (most recent call first):
3rdparty/SDL2/cmake_install.cmake:32 (include)
3rdparty/cmake_install.cmake:36 (include)
cmake_install.cmake:32 (include)
To fix this, I changed line 1770 from this:
${CMAKE_SOURCE_DIR}/SDL2Config.cmake
To this:
${CMAKE_CURRENT_SOURCE_DIR}/SDL2Config.cmake

When RWops seeks with fseek or fseeko it uses the types long or off_t which can be 32 bits on some platforms. stdio_seek does not check if the 64-bit integer for the offset fits into a 32-bit integer. Offsets equal or larger than 2 GiB will have implementation-defined behavior and failure states would be very confusing to debug.
The attached patch adds range checking by using the macros from limits.h for long type and some bit shifting for off_t because POSIX couldn't be bothered to specify min and max macros.
It also defines HAVE_FSEEKI64 in SDL_config_windows.h so that the Windows function gets picked up automatically with the default config.
And there's an additional error message for when ftell fails.

Since https://hg.libsdl.org/SDL/rev/6546daa45a02
SDL_android_main.c is empty and then produce a warning
nativeInit does not exist and dont need to be mark undefined
