The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-10/recipe-03 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.
We can imagine that our message library has been a huge success in the open source community. People like it a lot and use it in their own projects to print their messages to screen. Users particularly like the fact that each printed message gets a unique identifier. But users would also like the library to be more easily discoverable, once they compile and install it on their systems. This recipe will show how CMake can let us export our targets so that other projects using CMake can pick them up easily.
