Blender 2.9 CUDA on Mac

Hey Hugo, could you go into a bit more detail on this?

Note for the compilation: 2.93 uses python3.9, which in turns uses “__isPlatformVersionAtLeast”, a post-10.13 symbol, so I had to implement that from scratch.

• Copy __isPlatformVersionAtLeast from apple/llvm-project. DEVTOOLS-4987 · catboost/catboost@42bba6c · GitHub
• Compiling latest branch on MacOS fails (undefined symbol)

I managed to get a 2.93 Alpha build before, but now when I try to update & build again, I’m getting this error:

It’s because CMakeCache.txt has old variables/paths. Delete the file and start over.
