Installing on MacOS with Homebrew

LESGO comes with support for MacOS with libraries and dependencies installed using Homebrew. If some of these libaries or dependencies are already installed and you do not want to overwrite these using the Homebrew versions, some modification of the CMakeLists.txt file will be necessary.

1. Install homebrew from https://brew.sh/

2. Install gcc, open-mpi, fftw, and cmake in the terminal:

    brew install gcc
    brew install open-mpi
    brew install fftw --with-fortran --with-mpi
    brew install cmake
   

3. Change the environment flag for lesgo on line 14 of CMakeLists.txt to:

    set(hostname "darwin-brew")
   

4. Compile in terminal:

    ./build-lesgo
