mumps-solver provides CMake targets:

    find_package(unofficial-mumps-solver CONFIG REQUIRED)
    target_link_libraries(main PRIVATE unofficial::mumps-solver::DMUMPS)

MUMPS is written in Fortran, but the exported targets carry the Fortran runtime,
so C and C++ projects can link it without enabling Fortran themselves. For a
static MUMPS, the runtime is located with GNU Fortran, which must be on PATH.

mumps-solver also provides the pkg-config module unofficial-mumps-solver.

This port builds MUMPS in sequential mode; it uses the bundled MPI stub, whose
headers are installed to the "mumps_seq" include subdirectory.
