MPI not found on Ubuntu 20.04
I recently upgraded to Ubuntu 20.04. Since then, dunecontrol fails to detect MPI on my system:
-- Could NOT find MPI_C (missing: MPI_mpi_LIBRARY MPI_C_WORKS)
-- Could NOT find MPI_CXX (missing: MPI_mpi_LIBRARY MPI_CXX_WORKS)
-- Could NOT find MPI_Fortran (missing: MPI_mpi_LIBRARY MPI_Fortran_WORKS)
-- Could NOT find MPI (missing: MPI_C_FOUND MPI_CXX_FOUND MPI_Fortran_FOUND) I have the libraries installed, searching for *libmpi* gives
