>From http://makepp.sourceforge.net/ I read: "Makepp, a build program which has a number of features that allow for reliable builds and simpler build files, is a drop-in replacement for GNU make." Then why can't you use makepp with Makefiles generated by CMake? If Makepp cannot use them, then may be you can try to contribute a Makepp generator to CMake? If you are concerned with speed of build may be you can try the new Ninja generator. Concerning CMake vs (Make vs Makepp vs SCons) as Michael already mentionned, CMake cannot [easily] do "build-time" action, like hash computation, because it's a build **generator** not a build tool. -- Erk Le gouvernement représentatif n'est pas la démocratie -- http://www.le-message.org -- 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
