Adds the 'manifold' solver option to the Boolean geo node and to
the Boolean modifier. This solver is about as fast, or faster,
than the current float solver, and is robust against floating
point issues like the Exact solver. But currently it only
works on mesh arguments that are strictly manifold.
See https://projects.blender.org/blender/blender/issues/120182
for many more details.
This patch replaces our own FindTBB module with TBB's own TBBConfig
module. On the technical side of things, this harvests the TBB CMake
config modules, and switches our TBB CMake find_package calls from
Module mode to Config mode. Integration was done using OpenPGL as a
blueprint for parsing TBB target's property back into CMake variables
(TBB_LIBRARIES and TBB_INCLUDE_DIRS).

It's better for performance to use a single thread pool for all areas of
Blender, and this gets us closer to that.
Bullet, Quadriflow, Mantaflow and Ceres still contain OpenMP code, but it
was already disabled.
On macOS, our OpenMP libraries are no longer compatible with the latest
Xcode 16.3. By removing OpenMP we no longer have to solve that problem.
OpenMP was disabled for bpy module builds on Windows ARM64, which also no
longer needs to be solved.

OpenCollada used to rely on PCRE (a Perl Regexp library). Since
switching to Aras' OpenCollada fork (#122270), the library is no
longer needed, but is still required as a dependency.
This patch cleans this up by completely removing it from our build
system and linux system package installation script. This also lets
us remove it from our pre-compiled library platform repos, making the
process of recompiling our libraries from scratch easier as it wasn't
compiled by our dependency builder anymore.

That version has a bunch of API changes, so by dropping support for older
versions we can remove old compatibility code.
Also, that version is required for OptiX support, so building a fully-featured
Cycles wasn't possible with older OSL anyways.

* Some libraries like Alembic and OpenColorIO for a long time removed
header dependencies on Boost.
* No need to have BOOST_LIBRARIES anymore, only BOOST_PYTHON_LIBRARIES
is a direct dependency through USD headers.
* OpenVDB is no longer a static library, no need to link its dependencies.

While I implemented pipewire support I forgot that some of the functions I use is not available in older pipewire versions.
This adds proper library version sanity checks for pipewire.

This is not an officially supported platform, but it was working before
so might as well keep it up to date.
* Tweak logic for various BLENDER_PLATFORM_ARM checks
* Use linux_arm64 name for folders, matching Windows and macOS
* CUDA is enabled, SYCL and HIP are not
* Tested to work on Rocky Linux 8
This change switches Cycles to an opensource HIP-RT library which
implements hardware ray-tracing. This library is now used on
both Windows and Linux. While there should be no noticeable changes
on Windows, on Linux this adds support for hardware ray-tracing on
AMD GPUs.
The majority of the change is typical platform code to add new
library to the dependency builder, and a change in the way how
ahead-of-time (AoT) kernels are compiled. There are changes in
Cycles itself, but they are rather straightforward: some APIs
changed in the opensource version of the library.
There are a couple of extra files which are needed for this to
work: hiprt02003_6.1_amd.hipfb and oro_compiled_kernels.hipfb.
There are some assumptions in the HIP-RT library about how they
are available. Currently they follow the same rule as AoT
kernels for oneAPI:
- On Windows they are next to blender.exe
- On Linux they are in the lib/ folder

This reverts commit 0a0551cf26.
This commit broke building on linux with mold. It seems to never
generate the necessary file when something other than the `blender`
binary is the first thing being built.
Support manipulating symbols_unix.map using symbols_unix.map.cmake
script.
Currently this removes symbols that generate noisy warnings with the
mold linker.
Disable dynamic SDL loading as well as disable SDL for release builds.
This was only used for audio output which can already use OpenAL
if there are back-ends not natively supported by Blender.
- Remove extern/sdlew/
- Remove the WITH_SDL_DYNLOAD build option.
- Remove `bpy.app.sdl.available`.

Correct fix from [0].
The previous fix seemed to work but on further testing the environment
wasn't properly expanded. Using "$$" prefix resolves the problem.
[0]: b0ec4bba70
The value used for the the library path was being evaluated by CMake
instead of forwarding the value to the shell expression (as intended).
This meant any build-time binaries that depended on the environments
library-path would failed to run.
* Always define root directories in LIBDIR even when not needed,
to silence some warnings.
* Only show warnings about not finding libs when oneAPI is enabled.
* Prefix message for context.
When building a non portable build or when not using the precompiled
libraries, do not enable the CPU checker.
Make the cmake configure step error out when building with
WITH_STRICT_BUILD_OPTIONS if the LIBDIR can not be found.
