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 Windows binary with OpenMP parallelization

The code for this recipe is available at and has a C++ and Fortran example. The recipe is valid with CMake version 3.9 (and higher) and has been tested on GNU/Linux.

In this recipe, we will apply what we have learned in the previous recipe, albeit to a more interesting and realistic example: we will cross-compile a Windows binary which is parallelized using OpenMP.

Getting ready

We will use the unmodified source code from Chapter 3, Detecting External Libraries and Programs, Recipe 5, Detecting the OpenMP parallel environment. The example code sums up all natural numbers up to N (example.cpp...
