 if the plugin has been correctly installed, and thus find_package succeeds, then it will define two variables

-**IMPORTANT NOTE** For the time being, each plugin is only responsible for finding their own includes and library. This means that for instance wolfvision, which obviously requires
-the _core_ plugin, will not find its own dependencies. It is the responsibility of the programmer to do `find_package(wolf REQUIRED)` to get the includes and library. In the future this will change and each plugin will be responsible for finding all the necessary dependencies.
