We cannot generate dune.module because that file is read by dunecontrol before the build starts. It therefore make sense to let it be the original and let the build system read it instead of duplicating the information in CMakeLists.txt This module is a adaption of Andreas Lauser's OpmParseDuneModule in opm-material, modified to handle the more sparse info provided by the other modules as well.
