The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-10/recipe-04 and has a C++ example. The recipe is valid with CMake version 3.6 (and higher) and has been tested on GNU/Linux, macOS, and Windows.
Our example message library has become a huge success, and many other programmers use it and are very happy with it. You want to use it in your own project too, but are unsure how to manage the dependency properly. You could ship the source code for the message library with your own code, but what if the library is already installed on the system? Chapter 8, The Superbuild Pattern, showed that this is a typical scenario for a superbuild, but you are unsure on how to install such a project. This recipe will walk you through the details of installing a superbuild.
