CMake Cookbook

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.

Switching the build type

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.

CMake has the notion of build types or configurations, such as Debug, Release, and so forth. Within one configuration, one can collect related options or properties, such as compiler and linker flags, for a Debug or Release build. The variable governing the configuration to be used when generating the build system is CMAKE_BUILD_TYPE. This variable is empty by default, and the values recognized by CMake are:

  1. Debug for building your library or executable without optimization and with debug symbols,
  2. Release for building your library or executable with optimization and without debug symbols,
  3. RelWithDebInfo for...
