I have no experience with macOS development and XCode, but I figured that Homebrew installed the protobuf library in /opt/homebrew/Cellar/protobuf/3.19.4/lib so I added this path to Search Paths → Library Search Path.

That worked (Xcode found the library), but the Build process did not work. I get a lot of these error messages:

I'm using Apple Silicon.

I'm not sure if I can get it to work. It would easier if the binary would be made available (again) in the repository. It's not there anymore.
