Explanation

This rule searches for libraries in your Blueriq Model and reports back an issue when unused libraries are found. In case a library is connected to the project its modules should be used in the project. If it is connected, but not used the rule will trigger. However, there is an exception: there are libraries that does not contain modules, e.g. the AquimaLibrary which only uses globals. So this rule checks also if a library uses global elements.

Possible solutions

Try to add libraries only if they are really needed. If no elements are used, it is highly likely that the library can be removed from your project.
