 ## Usage
 
 To create an installable target for your current project, add the following to your CMakeLists.txt.
 This example assumes the project to be versioned and the name to be identical to the library to export.
-Also the [CPM.cmake](https://github.com/TheLartians/CPM.cmake) should be included.
