ARM/Silicon Mac Install Instructions

Hardware: Apple M1 Max MacBook Pro (2021) System: Ventura 13.6.2

Apple clang version 15.0.0 (clang-1500.0.40.1) Target: arm64-apple-darwin22.6.0 Thread model: posix InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I installed the following packages with homebrew (specified here), after having issues with cmake and nasm which caused the ffmpeg install to fail:

    brew install pkg-config
    brew install cmake
    brew install nasm
    brew install gcc
    brew install llvm
    brew install libomp
    brew install libmpc
    brew install tree

After cloning the repository in installation step 1B, I pulled the current master of oneTBB and replaced the submodule downloaded at PyPupilEXT/3rdparty/oneTBB. This was necessary because the Apple clang compiler failed with this issue, which has been fixed in subsequent releases.
My build finally compiled! Except when I tried to run the files, it threw an [ImportError: dlopen(): Symbol not found:.... Expected in: flat namespace] like this and this. I take it it was because PyPupilEXT specifies x86_64/x64 architectures for the compilers, but my clang was compiling for arm64.

So I changed setup.py as follows: line 81: cmake_args += ["-DVCPKG_TARGET_TRIPLET=arm64-osx"]
Along with CMakeLists.txt: line 60: set(VCPKG_TARGET_TRIPLET arm64-osx CACHE STRING "") line 61: set(CMAKE_OSX_ARCHITECTURES arm64 CACHE STRING "") line 80: CMAKE_ARGS -DTBB_TEST=OFF -DCMAKE_INSTALL_PREFIX=build -DCMAKE_OSX_ARCHITECTURES=arm64 -DBUILD_SHARED_LIBS=OFF -DTBBMALLOC_BUILD=OFF -DTBBMALLOC_PROXY_BUILD=OFF

And now it's running. I think those are all my emendations. Hope this is useful to someone!
