SIMD Everywhere finder needs to be installed alongside libobs CMake
package since its headers depends on it.
C++ cmath header is included on Windows on ARM to ensure that all math
functions are correctly defined when included in C++ code.
https://github.com/simd-everywhere/simde/issues/1304
macOS intrinsics is included to make sure that no redefinition error
happens.
With the removal of all legacy code paths, obsconfig.h always exists and
the compile definition always gets set. As such, it's no longer
necessary to check for it.
As removing the definition itself could be seen as a breaking change,
this simply moves the definition to pc.in and cmake.in files for now to
preserve the value for plugins that might expect this to be set. We may
remove the definition entirely in a later release.
That is, leave only the code that was under USE_XDG. Previously the
Linux CMake build defined USE_XDG unconditionally, while it was not set
by the FreeBSD build.
The non-USE_XDG code was broken, and FreeBSD should follow the XDG
convention anyway (in particular, storing config files typically under
$HOME/.config/obs-studio). Defining USE_XDG in the os-freebsd.cmake
files would leave the non-USE_XDG code unused anywhere, so instead just
remove it.
A recent obs-deps change removed all non-essential x86 deps. This caused
the x86 subproject(s) on Windows to fail to configure due to being
unable to find x86 dependencies that do not exist.

w32-pthreads is not correctly added to the generated CMake project
if the UI subdirectory is not also included, which leads to builds
configured without UI to fail.
One notable difference from the AVC/HEVC code is that it also inserts
the METADATA and SEQUENCE_HEADER OBUs into new_packet, otherwise the
resulting video file wouldn't play.
Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
clang expects an empty prototype to explicitly use `void`.
Also silences the warning in `libobs-opengl`, `obsglad`, `caption`,
`mac-syphon` and `obs-x264-test`.
Switching to a static library that contains version information as
const char strings has multiple benefits:
* The version information provided externally via compiler definitions
will fail compilation early if malformed
* An updated version string (which will happen with every commit) will
not invalidate existing compilation units, because only the static
library is affected by the change
* An update of the version change just requires a recompilation of the
static library and a linker update
* An update of the version will _not_ infect the rest of the codebase
(as it does currently, because everything includes obsconfig.h one
way or another)
* Other modules which used the macro definition directly have been
updated as much as possible to use the proper getter method from
`libobs` instead (some Windows-specific modules use preprocessor
string composition, the value has been added as a compiler definition
directly in those cases)
* Because the impact of a version change due to a commit hash change
is limited to the static library, ccache hit rates should be
improved considerably
