Hi James, I believe you're looking for the directory property CMAKE_CONFIGURE_DEPENDS ( https://cmake.org/cmake/help/latest/prop_dir/CMAKE_CONFIGURE_DEPENDS.html ). Adding a file path to that property causes any changes to that file to trigger a regeneration:
set_property(DIRECTORY APPEND PROPERTY CMAKE_CONFIGURE_DEPENDS version) If you are using CMake old enough not to have this property, an alternative workaround is to run configure_file() on the file (even if you never use the configured result). This will introduce the exact same dependency. Petr
