These instructions assume you are in your home directory.

1. Checkout Fenix sources
   • For example: git clone <address of this repo> && cd Fenix
2. Create a build directory.
3. Specify the MPI C compiler to use. Open MPI 5+ is the required version.
   • Check out the CMake documentation for the best information on how to do this, but in general:
     • Set the CC environment variable to the correct mpicc,
     • Invoke cmake with -DCMAKE_C_COMPILER=mpicc,
     • Add the mpi install directory to CMAKE_PREFIX_PATH.
   • If you experience segmentation faults during simple MPI function calls, this is often caused by accidentally building against multiple versions of MPI. See the FENIX_SYSTEM_INC_FIX CMake option for a potential fix.
4. Run cmake ../ -DCMAKE_INSTALL_PREFIX=... && make install
5. Optionally, add the install prefix to your CMAKE_PREFIX_PATHS environment variable, to enable find_package(fenix) in your other projects.
