[chuck-users] building chugins on Apple M1

[Ge Wang]

(FYI for macOS users are downloading and installing from the installer, 
universal binaries--intel and apple silicon--of the chugins are already 
included and installed with miniAudicle and command line chuck. A list 
of chugins currently included in the distribution can be found here: 
https://chuck.stanford.edu/doc/reference/chugins.html; a lot more is the 
way)

On macOS, the chugins architecture is controlled by the ARCHS variable, 
which by default is set to x86_64 (intel mac). You can build for 
different architectures by setting ARCHS before making, for example:

     (also 'make clean' before building for a different arch)
     ARCHS="arm64 x86_64" make osx

The above builds universal binaries. Alternately, to build for only 
Apple Silicon:

     (also 'make clean' before building for a different arch)
     ARCHS="arm64" make osx

I hope this helps!

Ge!
