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.

Generating sources at configure time

The code for this recipe is available at, including a Fortran/C example. The recipe is valid with CMake version 3.10 (and higher), and has been tested on GNU/Linux, macOS, and Windows with MSYS Makefiles.

The most straightforward code generation happens at configure time. For example, CMake can detect the operating system and available libraries; based on that information, we can tailor what sources are built, to offer maximum performance to the end user of our library or program. In this and some of the following recipes, we will illustrate how to generate a simple source file that defines a function to report the build system configuration.
