python freezing broken, make target VTK-ALL needs to be VTK_ALL
In the paraview repo at the tag for paraview 5.6.0 (v5.6.0 I think), the freeze python capability does not work. The issue seems to be with the make target named "VTK-ALL" (or vtk-all or Vtk-all). First, a regular expression searching attempt misses that target. Second, if the regular expression is fixed to capture VTK-ALL, the freezing fails because of having a dash/minus as part of a variable or function name or something. Changing the make target to have an underscore instead of a dash fixes the problem.
