harvesting openpgl_Exports-debug.cmake was missing for
windows in the build script, and we manually added it
to svn when openpgl landed when we realized it was
missing.
This fixes the issue at the root of the problem, so
the file will not be missing for future updates.
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.
This change adds support for intels cve-bin-tool [1]
in the deps builder. This adds 2 new targets to the
builder that do not build automatically but can be
build on demand when required.
`make cve_check` will output to the console.
`make cve_check_html` will output a html file that
can be shared with other people.
Requirements:
- A working installation of cve-bin-tool on the system
Not required but higly recommended:
- Obtaining a key from the nvd [2] to speed up the
database download. you can pass the key to cmake
using `-DCVE_CHECK_NVD_KEY=your_api_key`

When using pre-compiled libs, reference the bundled wayland headers,
needed so the headers from the bundled wayland-scanner are compatible.
Part of D16091.
The headers on centOS7 (Wayland 1.15) aren't compatible with the headers
generated by wayland-scanner 1.20.
Include the headers to support building Wayland on systems with
older Wayland installed.
Using these headers will be part of a separate commit.

It fixes SYCL runtime issues in Debug builds that were due to mixing
Release and Debug MSVC runtimes.
This commit also removes specific handling of dpcpp compiler executable
to simplify the CMake implementation. Using it like clang++ works and
clang++ executable is also available from Intel oneAPI DPC++ compiler in
case it doesn't.
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.

During the 3.3 release some packages were missing
in SVN during the release and it ended up building
the release tarball without issues when re-running
the `make source_archive_complete` command after it
failed initially. The tarball however had 0 byte files
for the missing packages.... not good.
This diff hardens the download process by :
1) Validating all required variables are set. This
catches the erroneously attempt at downloading the
nanovdb package even though we have removed it
from versions.cmake but neglected to remove it
from download.cmake
2) When a download fails (due to either a missing
package, or bad download URL) FILE Download will
warn about a hash mismatch but will carry on
happily, you then have to go into the file system
go delete the 0 byte file to retry the download.
We know for a fact the file is bad when it is 0
bytes, just delete it.
3) When we are using the blender repository
(and likely building a source archive) explicitly
validate the hash of all packages. Normally the
build process does this, however when building
a source archive the build does not actually
run for a dep. So preform this check during the
configuration stage.

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 adds path guiding features into Cycles by integrating Intel's Open Path
Guiding Library. It can be enabled in the Sampling > Path Guiding panel in the
render properties.
This feature helps reduce noise in scenes where finding a path to light is
difficult for regular path tracing.
The current implementation supports guiding directional sampling decisions on
surfaces, when the material contains a least one diffuse component, and in
volumes with isotropic and anisotropic Henyey-Greenstein phase functions.
On surfaces, the guided sampling decision is proportional to the product of
the incident radiance and the normal-oriented cosine lobe and in volumes it
is proportional to the product of the incident radiance and the phase function.
The incident radiance field of a scene is learned and updated during rendering
after each per-frame rendering iteration/progression.
At the moment, path guiding is only supported by the CPU backend. Support for
GPU backends will be added in future versions of OpenPGL.

This also reverts commit f6664217b3
"Build: temporarily disable wayland dependency".
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.
Also corrected bad indentation in: intern/cycles/CMakeLists.txt
- Add doc-string with example usage shown in the --help message.
- Add help text for command line arguments.
- Only search for the CMakeCache.txt file when the `--build-dir`
is omitted.
- Write fatal errors to the stderr.
The buildbot will call this script to create a binary .whl file that can be
easily installed through pip.
This wheel will only work with the same Python version used for Blender.

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.
Since this was added, Linux libraries have been included in `../lib/`.
This made `make bpy` on Linux install the `bpy` module into the bundled
SVN libraries which isn't very useful.
Now leave WITH_INSTALL_PORTABLE unset (defaulting to ON).
Python developers may reference their systems Python and disable the
option if they wish for a system-wide module installation.
As portable is already the default, setting it meant using the lite
configuration would always reset the value if was intentionally changed.
This was also inconsistent as other configurations left this unset.
