The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-06/recipe-06, including a C++ example. The recipe is valid with CMake version 3.5 (and higher), and has been tested on GNU/Linux, macOS, and Windows.
Most modern source code repositories are tracked using Git as version control system, a fact that can be attributed to the huge popularity of the repository hosting platform GitHub. We will, therefore, use Git in this recipe; the motivation and implementation will, however, translate to other version control systems.
