svn commit: r566983 - head/Mk/Uses

[Thierry Thomas]

Author: thierry
Date: Tue Mar  2 21:16:04 2021
New Revision: 566983
URL: https://svnweb.freebsd.org/changeset/ports/566983

Log:
  Adding a new helper for MPI.
  
  Its aim is to simplify the use of MPI in the ports Makefile.
  It makes it easier to provide an option for the user to choose between MPICH and
  OpenMPI when applicable.
  
  Note: mpich2 and openmpi3 are not handled, because they will be deprecated.
