cmake generates compiler options not supported

While compiling ParaView 5.9, my cmake (v3.19.2) generates compilation options which my compiler does not support. How can I prevent that?

cd /run/user/1100/ParaView/ParaViewBuild/VTK/Wrapping/Python && /scratch/e1000/jfavre/cmake-build/bin/cmake -E cmake_link_script CMakeFiles/pvtkpython.dir/link.txt --verbose=1

I guess we’re a bit greedy about adding that flag.

Cc: @utkarsh.ayachit @cory.quammen Probably something to look at for 5.9.0.

I have a candidate fix here: https://gitlab.kitware.com/vtk/vtk/-/merge_requests/7482
