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.
