 ## About
 
 Many open-source projects require adding a disclaimer to your binary reproducing the dependencies license. Finding and updating the disclaimer for all dependencies can be a tedious task. Luckily, if you've used [CPM.cmake](https://github.com/TheLartians/CPM.cmake) to add the dependencies this process can be automated.
 
-CPMlicenses.cmake will automatically scan all source directories of your CPM.cmake dependencies and find any file that begins with `LICENCE` or `LICENSE`, appending the contents to an output file that you can use as a license disclaimer.

If no license has been found for a package, a warning will be emitted.
