+raylib is configurable and can be be built in a variety of ways. Following is a listing of available CMake options and values, extracted from [`src/CMakeOptions.txt`](https://github.com/raysan5/raylib/blob/a1ec0a5bc33ab8726e55fa433ffc08fe3b42e539/src/CMakeOptions.txt).
+> **TIP**:  You can use the curses UI provided by `ccmake(1)` for interactively configuring raylib.
