They are not strictly needed for compilation and disabling them makes
the compiler more portable without any special trickery.
This change aimed to solve problem which currently happens on the API
documentation build which does not have terminfo installed, but needs
to compile Cycles.

min-driver version check can be worked around by setting

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).
rBb9c37608a9e959a896f5358d4ab3d3d001a70833 moved evaluation of
`versions.cmake` before `options.cmake`, as a result of which
`BLENDER_PLATFORM_ARM` was no longer defined in `versions.cmake`,
causing it to choose the wrong OpenSSL version for aarch64. This
reverts that. Also fixes a compiler crash when building flex with some
glibc versions.

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.

Latest OpenSubdiv builds without GLEW by default, which is also what we do
for precompiled libraries. So there is no need for compatibility checking
with system GLEW.
Additionally WITH_SYSTEM_GLEW is turned off by default for Blender, and this
logic was presumably added when it was still on by default a few years ago.
Also remove outdated mention of glew-mx, we use intern/glew-mx and no
external library for this.

* TBB MEX version is now 2021, since this versin introduces 'oneTBB'

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.

Following what is done for LLVM. Being consistent feels good here.
Not strictly needed as the build here passed anyway, but it does
feel good to be consistent.
llvm was using system python, rather than our copy
this went unnoticed on both linux and windows until
sergey tried to build the deps on a clean system with
no system python installed.
There is a check to be sure no system python is in the path
on windows to be sure deps do not accidentally build against it.
The problem arises on certain versions of windows that ship a
python.exe that just opens up the MS store to download their
python version. The check takes this to be a real python
installation and refuses to build.
This change fixes the issue by looking for pythonw.exe which a
real python install would have, but the MS store opening one that
windows ships (as of now) would not.
The following CMake options have been added (enabled by default),
except for the lite build configuration.
- WITH_IO_STL
- WITH_IO_WAVEFRONT_OBJ
- WITH_IO_GPENCIL (for grease pencil SVG importing).
Note that it was already possible to disable grease pencil export
by disabling WITH_PUGIXML & WITH_HARU.
This is intended to keep the lite builds fast and small for building,
linking & execution.

It can be assumed that all scripts comply with basic pep8 formatting

If we want to exclude some scripts from make format,
this can be done by adding them to `ignore_files` in:

Or using `# nopep8` for to ignore for individual lines.

When building blender as a python module, such as for inclusion in a
wheel, it is not permitted to link against python libraries.
This diff does so by simply unsetting the library when building blender
as a python module, instead of the more heavyweight solution of
switching to the cmake FindPython module.

OCIO could build before pystring and imath due to
OCIO missing the dependencies on these two projects
No rebuild required as the build would have failed
during the libs build if you ran into this issue.
The previous 3.1 libraries (accidentally) used glApi instead of GLEW and were
working for GPU subdivision, so revert to that. There's a suspected conflict
with Blender's own bundled GLEW or other issue with GLEW, causing the crash in
T97737.
The current GPU subdivision implementation does not need OpenCL, CUDA or GLFW.
So also remove libraries needed for that. It's simpler to stick to compute
shaders in OpenGL/Vulkan/Metal and not involve additional APIs.

`PXR_ENABLE_OSL_SUPPORT=OFF`: OpenShadingLanguage is an optional
dependency of the Imaging module. However, since that module was
included for its support for converting primitive shapes (sphere, cube,
etc.) to geometry, OSL is not necessary. Disabling it will make it
simpler to build Blender; currently only Cycles uses OSL.
`PXR_ENABLE_GL_SUPPORT=OFF`: GL support on Linux also links to X11
libraries. Enabling it would break headless or Wayland-only builds.
OpenGL support would be useful if someone wants to work on a Hydra
viewport in Blender; when that's actually being worked on, we could
patch in a new PXR_ENABLE_X11_SUPPORT option (to separate OpenGL from
X11) and contribute it upstream.
`PXR_BUILD_OPENIMAGEIO_PLUGIN=OFF`: It's used for loading image textures
in Hydra Storm / Embree renderers which we don't use.
