CMake Functions

CMake functions are reusable blocks of instructions used within CMake scripts to organize and streamline complex build configurations. Think of them as custom commands you create to perform specific tasks—like setting variables, adding files, or configuring build options—that can be called multiple times throughout a project. This helps make build scripts clearer, reduces repetition, and improves maintainability. Functions can accept inputs (arguments) and produce outputs, enabling flexible and modular control over the build process, ultimately simplifying the management of large or complex software projects.
