[Wannier] Compiling wannier90 on macosx with arm64 architecture

[Maksim Borovkov]

Hi Jerome,

yes, I installed openmpi via homebrew. In fact, I commented lines

"COMMS=mpi
MPIF90=mpifort"

from the make.inc file. If I do not comment out those, I receive these
errors (please see the screenshot).

Is there a way to check independently if MPI installed via homebrew works?

Max
