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.

Managing your project as a superbuild

The code for this recipe is available at and has a C++ example. The recipe is valid with CMake version 3.6 (and higher) and has been tested on GNU/Linux, macOS, and Windows.

ExternalProject and FetchContent are two very powerful tools in your CMake arsenal. The previous recipes should have convinced you how versatile the superbuild approach is in managing projects with complex dependencies. We have so far shown how to use ExternalProject to handle the following:

  • Sources stored within your source tree
  • Sources retrieved from archives available on online servers

The previous recipe showed how to use FetchContent to handle dependencies available from open source Git repositories. This recipe will show how to use ExternalProject to the same effect. This last recipe will...
