My guess is you need to add the plugin via a C++ project, inside the file as outlined here under the Dependencies section
Well, i realize my comment is a bit redundant, also looking for a solution without resorting to using a C++ project. At least i would had wished to know this plugin speciality before investing so much time bothering with a standard project. Because it seems to be kind of a task to “switch”, so not entirely sure how much work this actually is. Maybe using C++ is better after all …
