AutoMPI not working with OpenMPI
On ArchLinux and Ubuntu 20.04, when building and using ParaView with AutoMPI and OpenMPI is not working and displays the following output :
[glow@snowman ~/work/paraview/paraviewThird/paraview_build]$ ./bin/paraview AutoMPI: SUCCESS: command is: "/usr/bin/mpiexec" "-np" "2" "/home/glow/work/paraview/paraviewThird/paraview_build/bin/pvserver" "--server-port=38647" AutoMPI: starting process server AutoMPI: server never started. vtkProcessModuleAutoMPIInternals: Server never started. Generic Warning: In /home/glow/work/paraview/paraviewThird/paraview/ParaViewCore/ServerManager/Core/vtkSMSession.cxx, line 307 Failed to automatically launch 'pvserver' for multi-core support. Defaulting to local session.
kwSys seems fails to run the command for some reason.
