[Paraview] ctests linked to mpi failing when not launched with mpiexec

[Burlen Loring]

Hi,

On hopper, nautilus, and very likely most other supercomputers 12 of the 
19 ctests that are available when using pv without x11 are failing 
because mpi is linked in but the appropriate mpiexec command is not used 
to launch the test. for eg: 
http://open.cdash.org/viewTest.php?onlyfailed&buildid=2527186 Would it 
be reasonable to launch these with "mpiexec" when pv is compiled with mpi?
