Add a macro that implements something similar to cmake_path's IS_PREFIX
which isn't supported in older versions of CMake.
This caused the build-bot to fail.
This is to help ensure buildbot builds are correct, while still gracefully
disabling features in user/developer builds.
* Add WITH_STRICT_BUILD_OPTIONS to give an error when features can't be
enabled due to missing libraries or other reasons. Add new macro
set_and_warn_library_found used everywhere features were being
automatically disabled.
* Remove code from Windows and macOS for various libraries that would
automatically disable features. set_and_warn_library_found could be
used here also, but we are generally assuming the precompiled libraries
are complete and only test for availability when libraries are just
added.

For some compiler and linker configurations, linking would fail as the
wayland libs were linked at a high level and not at the actual code
where they were needed.
After talking to Campbell, we decided to clean up this part and now
only link both the X11 and Wayland libs where they are used.
When using pre-compiled libs, reference the bundled wayland headers,
needed so the headers from the bundled wayland-scanner are compatible.
Part of D16091.
This is a minimal set of changes, allowing a lot of cleanup that can
happen afterward as it allows sycl method and objects to be used outside
of kernel.cpp.

To avoid issues with install_deps. If we more generally switch to using
CMake configs then perhaps this code can be deduplicated again or at
least simplified.
This is needed to ensure and up to date "wayland-scanner" is used,
as versions before 1.20.0 generate headers incompatible with
dynamic linking (WITH_GHOST_WAYLAND_DYNLOAD).
As the centos7 version of wayland is 1.15 so make this part of Blender's
dependencies on Linux.
We intend to enable Wayland for Blender 3.4 release, this is needed for
the build-bot.

Match minimum supported versions from the WIKI [0] by raising them to:
- GCC 9.3.1
- CLANG 8.0
- MVCS 2019 (16.9.16 / 1928)
Details:
- Add CMake checks that ensure supported compiler versions early on.
- Previously GCC per-processor version checks served to exclude
`__clang__`, in some cases this has been replaced by explicitly
excluding `__clang__`. This was needed as CLANG treated some of these
flags differently to GCC, causing the build to fail.
- Remove USE_APPLE_OMP_FIX GCC-4.2 OpenMP workaround.
- Remove linking error workaround for old MSVC versions.

This is already the case for most CMake usage.
Although some find modules are an exception to this, as they were
originally maintained externally they use some different conventions.

A continuation of previous fix for malloc hooks which got removed
from the new glibc library.
The pre-compiled jemalloc has definitions which interpose hooks
in glibc leading to linking errors with multiple hook definitions.
A simple fix is to skip doing the workaround when using jemalloc
from pre-compiled libraries.
This will likely be revisited in the future, but for now it is
important to fix compilation errors for developers.
Same as other build options, don't make it a hard requirement to have
Wayland libraries installed when it gets enabled by default.
Also fixes wayland-protocols not being found on the buildbot.
PLATFORM_BUNDLED_LIBRARIES gathers shared libraries that will be installed
to the lib/ folder. The Blender executable gets a relative rpath pointing to
this folder as part of the install step.
The build rpath is different and uses absolute paths, so that it works for
executables like tests that are in different locations, and to support the
case where the build and install folders are different.
The system is already used for the OpenMP library on macOS. But on Linux it
will only kick in once we start using shared libraries for dependencies.
This also removes Mesa libraries from the old location, as these would cause
Blender to start with software OpenGL.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

Because of the recent changes to our core fonts,
Freetype has to support Woff2 fonts or Blender will segfault on startup.
This adds an explicit check for this to inform people compiling Blender
about this requirement.
Instead of specifying which symbols to hide, we hide all and make a few
visible. Some users may be relying on calling internal Blender functions,
but Windows is already hiding all of them and this is just not supported.

This is a refresh of our current FFmpeg 5.0.0 (unchanged) version with the
following changes:
* libvpx all platforms: enable SSE3/4/AVX/AVX2 instruction sets. libvpx has a
proper CPUID check in place and will not call the faster kernels unless it is
sure the CPU supports it. So we can safely enable this, this partially
resolves T95743 (completely on Linux and macOS).
* libvpx Windows - threading was disabled due to a shared dependency on
libwinpthreads.dll which we prefer not to distribute. However when configure
cannot find pthreads it will happily fall back on a win32 threads based
emulation layer. This also resolves the final part of T95743.
* libaom-av1 - new dependency required for D14920, this is a somewhat odd
dependency, it's cmake based, but still needs the perl environment setup, so
we have to setup the env and call cmake our selves for the configure, build
and install commands. This dep has the same libwinpthreads issue as vpx on
Windows, however since it's cmake based, it's easier to prevent cmake from
detecting it.

Add intern/wayland_dynload which is used when WITH_GHOST_WAYLAND_DYNLOAD
is enabled (off by default). When enabled, systems without Wayland
installed will fall back to X11.
This allows Blender to dynamically load:
- libwayland-client
- libwayland-cursor
- libwayland-egl
- libdecor-0 (when WITH_GHOST_WAYLAND_LIBDECOR is enabled).
This patch adds a new Cycles device with similar functionality to the
existing GPU devices. Kernel compilation and runtime interaction happen
via oneAPI DPC++ compiler and SYCL API.
This implementation is primarly focusing on Intel® Arc™ GPUs and other
future Intel GPUs. The first supported drivers are 101.1660 on Windows
and 22.10.22597 on Linux.
The necessary tools for compilation are:
- A SYCL compiler such as oneAPI DPC++ compiler or
https://github.com/intel/llvm
- Intel® oneAPI Level Zero which is used for low level device queries:
https://github.com/oneapi-src/level-zero
- To optionally generate prebuilt graphics binaries: Intel® Graphics
Compiler All are included in Linux precompiled libraries on svn:
https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for
Windows precompiled binaries but for the graphics compiler, available
as "Intel® Graphics Offline Compiler for OpenCL™ Code" from
https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html,
for which path can be set as OCLOC_INSTALL_DIR.
Being based on the open SYCL standard, this implementation could also be
extended to run on other compatible non-Intel hardware in the future.

Add WITH_GHOST_WAYLAND_DBUS option, so Blender can be built without
DBUS support. Currently it's only used to access the cursor theme.
Without this the "default" cursors are used instead.
Disabling this since it adds an additional dependency for a minor gain
in functionality, with the benefit of removing a library requirement.
There is also a problem where Blender hangs on startup for ~5 seconds
when DBUS isn't running. Eventually it would be good to be able to avoid
this problem without a build option.
This implements client-side window decorations for moving and resizing
windows and HiDPI support.
This functionality depends on the external project 'libdecor' that is
currently a build option: WITH_GHOST_WAYLAND_LIBDECOR.

This reverts commit 086f191169.
There was apparently a problem using APPEND which wasn't referenced
in the commit log.
Added comment noting the reason for the discrepancy.
This was already done for APPLE & WIN32, which would
reference these libraries twice.
Now append BROTLI_LIBRARIES to FREETYPE_LIBRARIES when they're
required for linking.
No functional changes as all references to FREETYPE_LIBRARIES also
used BROTLI_LIBRARIES.
When LIBDIR existed, searching for system libraries would always
first search 'LIBDIR'.
This meant "WITH_SYSTEM_*" would still prefer LIBDIR versions of
libraries if they exist.
The presence of LIBDIR also ignored the setting for WITH_STATIC_LIBS
which is now restored to the cached value once pre-compiled libraries
have been handled.
The Brotli library only needs to be explicitly linked when using the
statically linked libraries. When using system libs they're shared, and
the .so loading mechanism takes care of dependencies.
Add `libbrotlidec-static.a` and `libbrotlicommon-static.a` to the CMake
`$FREETYPE_LIBRARIES` variable; they'll be required when the Linux libs
for the FreeType upgrade lands (D13448).
The order of libraries is different compared to the similar lines in the
Windows and Apple CMake files, to prevent linker errors on Linux.
Since the option to enable linkers are booleans,
it's possible to enable them all at once.
Now only the first enabled + available linker is used
(with priority given to link is with better performance).
