If Python3 is turned off, ParaView fails on install
If you turn Python3 off (no clue why yo), the Paraview make won't make pvbatch or pvpython. make install will try to install pvbatch and pvpython - and will then die. Here are the switches I (accidentally) flipped:
I did NOT have '-DENABLE_python3:BOOL=ON '
I DID have '-DUSE_SYSTEM_python3:BOOL=ON '
I DID have '-DENABLE_python:BOOL=ON '+
and '-DENABLE_numpy:BOOL=ON '
