macOS: cmake detect system processor incorrectly on Apple Silicon?

I think there is a way for a x86_64 process to tell what the underlying processor is even when running under Rosetta.

Yes, but when executing a process, you’ll get the x86_64 version, so it will be “cross compiling” as far as any tooling is concerned. It’s just easier to get a multi-arch CMake instead.
