I'm not sure ccache replaces hash. My understanding is that ccache speed up individual compilation, but all the targets that depends on it are still compiled. With hash, a file is checked first whether it should be recompiled, if not, it will not be recompiled, and all the targets that depend on it will not be compiled either. I'm not with a machine that I can check ccache as this moment. Please correct me if I'm wrong. The following compares a few features. But since it is from waf, it might be biased in favor of waf. Nevertheless, there are some features that available in other tools missing in cmake. http://code.google.com/p/waf/wiki/WafAndOtherBuildSystems -- Regards, Peng -- 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
