With CMake, you no longer need to maintain separate settings specific to your compiler/build environment. Such as make, Apple's Xcode, and Microsoft Visual Studio. It is used in conjunction with native build environments It is designed to supportĭirectory hierarchies and applications that depend on multiple There are many questions asked by CMake newbies like me that don't ask this explicitly, but that make obvious the fact that, as newbs, we have no idea how to deal with CMake or what to make of it.ĬMake is software for managing the build process of software No matter what tutorials I read, I feel like I'm missing something important. None of the tutorials, documentation pages or questions/answers I've seen so far give any useful insight towards understanding how to use CMake. What's the difference between specifying how to build an executable or library from the CMakeLists file in their own subdirectory versus doing it in the CMakeLists file at the root of all source?Ĭan I make a project for Eclipse and another for Visual Studio, just changing the -G option when calling CMake? Is that even how it's used? Why does each subdirectory need its own CMakeLists file? Would it make sense to use CMake on a CMakeLists.txt other than the one at the root of the project? If so, in what cases? What does calling CMake on a CMakeLists mean? Is it supposed to be called once per build tree or what? How do I use different settings for each build if they all use the same CMakeLists.txt file from the same source?
