I followed the instructions to brew install the deps and git clone in recursive mode and then build in sequential model (without -j 4) make it easier to find the first error message, which is the following:

Sorry for taking so long to reply. I haven't been able to test it on an M1 mac but the latest commit c85b83e072a294f1b71151f5c5b6c46e27afd566 should fix the issue!
