This script helps you easily build universal static libraries for macOS.
It takes two directory trees, containing the libraries and any other files for each architecture (e.g. x64 and ARM) and then merges them to produce a single directory with the universal binary.
While traversing both directory trees, all files which are static libraries (.a files) or mach-O binaries (Typically .dylib or executable) are looked up in the second directory tree and both versions are merged using lipo. Any other files will be copied into the target directory.
Run it like this:
$ python3 lipo-dir-merge.py <arm64-dir-tree> <x64-dir-tree> <universal-output-dir>
