Enabling all `make deps` dependencies with the exception of Embree and OIDN.
After that, Blender can be compiled on an Apple Silicon Mac just like on any
Intel based Mac. There are still compiler warnings that need to be
investigated and there are probably a couple of bug still to be discovered
and to be fixed.
Most patches to the dependencies are simple and are about disabling SSE and
setting the proper architecture to compiile for. Notable exception is Python,
where I back ported a yet to be accepted PR for upstream Python:
https://github.com/python/cpython/pull/21249
Cross compiling or buliding a Universal Binary is not supported yet.
The minimum macOS target version for x86_64 remains at 10.13, the target
for arm64 is 11.00.

The configuration was confused about gettext installed via Homebrew
and isysroot passed to Python's compilation but not to test programs.
After this change `import gettext` still works, but it is unclear how
to test it further,

Mainly this is following Linux to build own xml2/lzma/ssl/sqlite and linking
them all statically. This ensures the Python ssl module uses a recent openssl
version rather than a very old one shipped with macOS.
There is system-wide libz development package installed by default,
needed for some other dependencies. This patch ensures Python will
use our own self-compiled Zlib.
This involved getting SSL compiled from sources first, ensuring
it is a static library placement independent code. Configuration
is based on what Debian is using. CFlags required to have own
configuration file, which i didn't find a better place that next
to the corresponding CMake file.
It is OpenSSL btw.
It is set to Python via --with-openssl= configuration argument.
This works fine in a clean chroot, but having libssl-dev installed
might make Python to prefer system wide library, This was worked
around by using libssl_pic.a name for the library and modifying
setup.py. Would be cool to ensure system wide libraries are not
a problem, but official release builder is safe against this,
since it will catch possible non-static dependencies.
There is also a new map file which shadows bunch of Python
symbols. Without this Python's shared libraries might bring
conflicting symbols to Blender namespace at runtime.
Hopefully this doesn't break other platforms.
-No more hardcoded python35/36 tokens in the scripts
-disabled python module for boost, was not used
-Updated patches for python to support building with msvc2013
We stop using the .zip file and just have all files now in
lib/darwin/python/lib, along with numpy, numpy headers and requests.
This makes it consistent with Linux and simplifies code.
For old libraries the .zip stays, code for that gets removed when we
fully switch to new libraries.
Note these are intended for platform maintainers, we do not intend to
support users making their own builds with these. For that precompiled
libraries from lib/ should be used.
Implemented by Martijn Berger, Ray Molenkamp and Brecht Van Lommel.
