• [gentoo-dev] Reliably find MPI implementation

    From Alessandro Barbieri@21:1/5 to All on Wed Jun 8 19:20:01 2022
    I have a package that uncorrectly guesses the mpi implementation because
    it's grepping the /usr/include/mpi.h and since it's a multilib wrapper, it doesn't contain the defines. I can specify the mpi implementation while configuring.

    How to reliably detect the MPI implementation?
    I need something (eclass ?) that return one the following: openmpi/mpich/mpich2/mpich3/lam/etc. based on the current installed status
