[Paraview-developers] Change in mpi operation of paraview and pvpython in ParaView 5.5.0-RC1-1

[Hennessey, Joseph G CTR USARMY RDECOM ARL (US)]

Hello,

I have noticed that when building ParaView 5.5.0-RC1-1 with an external
MPI version that pvpython and paraview itself are now being built such
that they can not be executed without mpirun.

For example this would work with ParaView 5.4.1

paraview
pvpython
mpirun -n 1 pvbatch

While for ParaView 5.5.0-RC1-1 I have to do the following

mpirun -n 1 paraview
mpirun -n 1 pvpython
mpirun -n 1 pvbatch

as running

paraview
pvpython

without mpirun will no longer work and complain about 
attempting to run an mpi required program without mpi,
as has been the case with pvbatch in the past.

Is this an intentional change, or is this an unintended consequence
of some other change?

Thanks,

Joe
