Instead of listing the CPack configuration settings in CMakeCPack.cmake as we have done for simplicity, we could have placed the per-generator settings of CPACK_* variables in a separate file, such as CMakeCPackOptions.cmake, and included these settings into CMakeCPack.cmake using set(CPACK_PROJECT_CONFIG_FILE "${PROJECT_SOURCE_DIR}/CMakeCPackOptions.cmake").
