As with any advice you get from me, you should double-check it before you use it :). I'm not guaranteeing that changing the cache during a build will trigger a CMake rebuild. Note also that doing a multi-thread compile (make -j) may cause your CMake rebuild to happen at inconsistent times. tyler _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
