Installation on macOS arm64

Prerequisites

The only prerequisites needed are CMake and MPI, and the easiest way to get them on macOS is via Homebrew.

First, install Homebrew with:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

then you can install CMake and Open MPI with:

brew install cmake open-mpi
