Question: On how to build for arm64

[fbalicchia]

Hi,
first of all thanks for your work, I've opened di question to have some tips on how I can build this extension for macOS-arm64.
When I try to build it I receive the following error
ld: warning: ignoring file libdeltatable.a, building for macOS-arm64 but attempting to link with file built for macOS-x86_64

Thanks for help
