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`__clang__`, in some cases this has been replaced by explicitly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.
Also corrected bad indentation in: intern/cycles/CMakeLists.txt
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

- 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).
Set the linker using CMAKE_*_LINKER_FLAGS instead of {C/CXX}FLAGS.
There is no advantage in using the CFLAGS to set the linker, it has the
downside of triggering a full rebuild when changing the linker.
Tested building Blender and the bpy.so Python module.

This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.
I would like to give a huge thanks to @JacquesLucke who helped during this
and pushed me to reduce the duplication further.
