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.

Defining a unit test and linking against Google Test

The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-04/recipe-03, and has a C++ example. The recipe is valid with CMake version 3.11 (and higher), and has been tested on GNU/Linux, macOS, and Windows. The code repository also contains an example compatible with CMake 3.5.

In this recipe, we will demonstrate how to implement unit testing using the Google Test framework, with the help of CMake. In contrast to the previous recipe, the Google Test framework is more than a header file; it is a library containing a couple of files that need to be built and linked against. We could place these alongside our code project, but to make the code project more lightweight, we will choose to download a well-defined version of the Google Test sources at configure time, and then build the framework...
