The object files of consuming targets might use headers generated by custom commands in earlier targets. The order-only dependencies ensure a safe build for such cases. They are not always needed, and the extra dependencies could be removed with sufficient work on the generator. See these issues: Optionally disable build order dependency target_link_libraries http://www.cmake.org/Bug/view.php?id=13799 target_link_libraries may have option not to add dependencies, for archive target http://www.cmake.org/Bug/view.php?id=14726 Generalize LINK_ONLY http://www.cmake.org/Bug/view.php?id=14751 and a workaround mentioned here: http://www.cmake.org/Bug/view.php?id=14726#c35023 -Brad -- 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.
