The Philosophy of Modern CMake Why "Effective CMake"? Just like with C++, the way you write CMake code significantly impacts your project's maintainability, ease of use for others, and scalability. Adopting modern practices is key. CMake is Code Treat your CMakeLists.txt files with the same care as your source code. Apply principles like Don't Repeat Yourself (DRY), keep it clean, and write comments where necessary. 2. The CMake Language: A Quick Tour Organization CMake code can be organized in three ways: Directories (CMakeLists.txt): The entry point for a project or sub-project. add_subdirectory() adds another directory (which must contain a CMakeLists.txt) to the build. Scripts (<name>.cmake): Executed with cmake -P <script>.cmake. They are useful for automation but cannot define build targets like executables or libraries.
