Cross compile for aarch64 on Ubuntu

It’s an amd64 system, compiling for arm64/aarch64. I think Ubuntu could just install packages into /usr/aarch64-linux-gnu/{lib, include, bin}, but there’s probably a reason they don’t.

Anything I can do? I am not familiar with the CMake codebase at all.

Any workarounds I could use for now?

Thanks!
