Why re-invent the wheel? Make already does a lot of things quite well. CMake builds on that. 2. Remember that CMake doesn't only work with Make. It can generate Visual Studio projects and drive several other build systems. CMake isn't a build system itself; it's meant to provide a common mechanism to abstract code organization away from the underlying build system. 3. There's a lot of things CMakeLists might do that aren't directly build-related, such as creating test configurations and identifying platform-specific dependencies. There's no need to go through all those steps every time you just want to compile your latest change; it makes sense to have a separate configuration step for those. There have been several other projects which attempted to be a "better Make" which is effectively what you're describing. There's nothing wrong with that, but that isn't what CMake does. If that's what you want in a tool, then I think you'll be happier finding a tool with that goal - always pick the right tool for the job at hand! Ceej aka Chris Hillery
