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.

Cross-compiling a hello world example

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

In this recipe, we will reuse the "Hello World" example from the previous recipe and cross-compile the code from Linux or macOS to Windows. In other words, we will configure and compile the code on Linux or macOS and obtain an executable for the Windows platform.

Getting ready

We start with a simple hello world example (hello-world.cpp):

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

const std::string cmake_system_name...
