This is an old module from when VTK and other Kitware projects drove the addition of commands and modules into CMake itself. Modern VTK doesn't need this module and it can be ignored. This module is kept around so that the ancient VTK versions which use it are not broken by it. VTK itself stopped using the module in 2012 and the last usage by an example in VTK was removed in 2020. Fixes: #20591
