The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-05/recipe-02. The recipe is valid with CMake version 3.5 (and higher) and has been tested on GNU/Linux, macOS, and Windows.
Running CMake generates the build system, thus specifying what commands the native build tools will have to execute to get your project built, and in which order. We have already seen how CMake runs many subtasks at configure time in order to find out the working compiler and necessary dependencies. In this recipe, we will discuss how to run custom commands at configure time by using the execute_process command.
