Cmake cannot locate VTK, VTK installation incomplete, VTK and paraview conflict

There is. They both provide the vtk Python module. ParaView installs its VTK configuration in a subdirectory of its own. There should be a /usr/lib/*/cmake/paraview-*/vtk path you can pass as VTK_DIR to use the VTK that comes with the ParaView package. You’ll need the -dev packages to provide these files.
