Build against Python from precompiled libraries by default, instead of
requiring framework from python.org package install. The resulting bpy module
can still be used with any Python install of the same version.
Use the same CMake find module as Linux. This simplifies code, and makes it
possible to manually set PYTHON_* variables in CMake configuration.
Remove WITH_PYTHON_FRAMEWORK option for regular Blender build, as this doesn't
work well due to missing required Python packages. Advanced users can still
set PYTHON_ROOT_DIR=/Library/Frameworks/Python.framework/Versions/3.10 for
the same result.
Replace the argument with an in ifdef in BKE_appdir_program_path_init.
At the time `blenkernel` didn't define WITH_PYTHON_MODULE, since it does
now there is no need for an argument. With the minor benefit of fewer
preprocessor checks in the main() function.
Building WITH_PYTHON_MODULE was creating a "bpy" module that required
Blenders data-files to be located in the module search path too.
This mean that a typical installation on Linux would create:
- `/usr/lib/python3.10/site-packages/bpy.so`
- `/usr/lib/python3.10/site-packages/3.4`
(containing `scripts` & `datafiles`).
The new behavior creates:
- `/usr/lib/python3.10/site-packages/bpy/__init__.so`
- `/usr/lib/python3.10/site-packages/bpy/3.4`
With the advantage that the "bpy" directory is the self contained Python
module.
No changes are needed for the module loading logic as the mechanism to
swap in blend internal Python "bpy" module
(defined in `release/scripts/modules/bpy/__init__.py`)
works the same in both instances.
Thanks to Brecht for macOS support.

BKE_appdir_program_path_init would override the module path extracted
from the Python module, replacing it with the Python executable.
This caused the data files not to be found and the module not to load.
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.

Instead of using macros like GLIBC we can use the CMake build
systems internal functions to check if some header or functions are
present on the running system's libc.
Add ./build_files/cmake/have_features.cmake to add checks for
platform features which can be used to set defines for source
files that require them.

The original intention from [0] was to force background-mode when built
WITH_HEADLESS or WITH_PYTHON_MODULE, with the else clause setting the
signal handler for Ctrl-C. Since WITH_PYTHON_MODULE now disables all
signal handlers this check no longer makes sense.

This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.
One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.
These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

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.

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.
Fixes T99900: crash with some third-party Python libraries since OneAPI
Ref T76442
Differential Revision: https://developer.blender.org/D14971
Allows to put libraries which are always needed by Blender into the
lib/ folder and not worry about OpenGL libraries picked up from there.
Currently no functional changes as we do not yet have dynamic libraries
which we load at startup. It allows to use direct linking of oneAPI
Cycles device (see D15397), also it is something which would need to
happen to support USD/Hydra/TBB compiler as dynamic libraries in the
future.
Differential Revision: https://developer.blender.org/D15403
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.

Building against the existing 3.1 libraries should continue to work, until
the precompiled libraries are committed for all platforms.
* Enable WebP by default.
* Update Windows for new library file names.
* Automatically clear outdated CMake cache variables when upgrading to new
libraries.
* Fix static library linking order issues on Linux for OpenEXR and OpenVDB.

Also fixes missing code to read/write/free/copy color management settings
in various places. This can't be set through the UI currently, but still
should be handled consistently.
This is supposed to hold the latest improvement from the EEVEE rewrite branch.
Note that a restart is necessary in order for the engine to appear.
The registration code is a bit convoluted as it needs to be after the WM_init.
Brew's Python framework's site-packages is a symlink so the assumption
that Resources and site-packages would be in the same directory
doesn't hold. So install scripts etc relative to bpy.so. Part of D14111
Since the output file stays unmodified for most developer builds,
install step installed it redundantly.
Create readme.html using `configure_file`:
- Now it's modified only if final output changes (handled by CMake).
- If input file (from git) or blender version changes,
it //will// be modified.
Also don't re-implement what CMake can do.
