In CustomInteractorStyle.h, you should forward declare CustomWidget.
That is, replace this line:

#include "customwidget.h"

with

class CustomWidget;

Let us know if it works. If it does not, please provide a minimal
compilable example so we can reproduce the error (a single file that
we can copy+paste+compile).
