Specifying rules for different libraries: how to import the dependent classes?

[rbonifacio]

When specifying rules for Google Tink, I had to import several JAR files to the scope of the Eclipse project. For this particular case, I created a maven project with a dependency to the Google Tink's maven artefact. Not completely sure if this is the better approach. After discussing with @johspaeth , we decided that we should open an issue about this.

Extending this discussion a bit, what should we do when specifying rules for C/C++? Considering the particular case of C language, the events will not be defined in the scope of a class/object.
