CMake Cookbook

By: Radovan Bast, Roberto Di Remigio

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.

Specifying the compiler

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

One aspect that we have not given much thought to so far is the selection of compilers. CMake is sophisticated enough to select the most appropriate compiler given the platform and the generator. CMake is also able to set compiler flags to a sane set of defaults. However, often we wish to control the choice of the compiler, and in this recipe we will show how this can be done. In later recipes, we will also consider the choice of build type and show how to control compiler flags.
