Error on compiling vtkDIYUtilities.cxx from the current ParaView 5.8.0 git master with gcc 6.3.0 or gcc 7.3.0 on RHEL 7.7 and SGI’s MPI version mpt/2.15, mpt/2.17 or mpt/2.21

vtkDIYUtilities.cxx is not working when using an external MPI version complaining about, among other things, `error: ‘friend’ used outside of class` included from `vtkMPI.h.

This file is new to ParaView 5.8.0 and I am not sure how to address this issue which is preventing using of external MPI versions that are needed for high efficiency on our super computers.

Thanks,

Joe Hennessey
