  -gcc              force g++ instead of the value from \$WM_CXX
  -verbose          verbose output in Makefiles
  -version VER      specify an alternative version (current value: $ParaView_VERSION)
  -major   VER      specify an alternative major version for special builds
  -mesa-include DIR
                    location of mesa headers (current value: ${MESA_INCLUDE:-none})

  -python-lib PATH  path to python library   (current value: ${PYTHON_LIBRARY:-none})
  -help

The -no-FEATURE option can be disable these features (if not already disabled):
  mesa mpi python qt

CMake options start with a capital letter and contain an '='.
For example,
    $Script BUILD_TESTING=ON
to add tests

For finer control, the build stages can be selected or deselected individually:
  -config    -no-config
  -make      -no-make
  -install   -no-install


* Make and install paraview-$ParaView_VERSION located under
      \$WM_THIRD_PARTY_DIR/ParaView-$ParaView_VERSION
  ->  \$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/paraview-$ParaView_VERSION
