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.

Compiling a single source file into an executable

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

In this recipe, we will demonstrate how to run CMake to configure and build a simple project. The project consists of a single source file for a single executable. We will discuss the project in C++, but examples for C and Fortran are available in the GitHub repository.

Getting ready

We wish to compile the following source code into a single executable:

#include <cstdlib>
#include <iostream>
#include <string...
