CMake Cookbook

Overview of this book

CMake is cross-platform, open-source software for managing the build process in a portable fashion. This book features a collection of recipes and building blocks with tips and techniques for working with CMake, CTest, CPack, and CDash. CMake Cookbook includes real-world examples in the form of recipes that cover different ways to structure, configure, build, and test small- to large-scale code projects. You will learn to use CMake's command-line tools and master modern CMake practices for configuring, building, and testing binaries and libraries. With this book, you will be able to work with external libraries and structure your own projects in a modular and reusable way. You will be well-equipped to generate native build scripts for Linux, MacOS, and Windows, simplify and refactor projects using CMake, and port projects to CMake.

Splitting CMake sources into modules

The code for this recipe is available at The recipe is valid with CMake version 3.5 (and higher) and has been tested on GNU/Linux, macOS, and Windows.

Projects typically start with a single CMakeLists.txt file, but over time this file grows and in this recipe we will demonstrate one mechanism for splitting CMakeLists.txt up into smaller units. There are several motivations for splitting up CMakeLists.txt into modules that can be included in the main CMakeLists.txt or other modules:

  • The main CMakeLists.txt is easier to read.
  • CMake modules can be reused in other projects.
  • In combination with functions, modules can help us limit the scope of variables.

In this recipe, we will demonstrate how to define and include a macro that allows us to get colored CMake output (for...
