Have you considered using the Ninja generator? It does have dependency information right from the compiler (via the `-M` flag family). --Ben -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
