Apple M1: Enable CMake cross compilation

Browse source 
Modify the build script to use CMake's cross compilation infrastructure instead
of running CMake natively in x86_64 and arm64 mode to configure the two project
files. This should fix the builds with CMake executables installed through
homebrew and should pave the way for building universal binaries on x86_64
systems.
