Putting hyphens in library names is just ugly, when the rest of the
product name is neat and tidy CamelCase with an initial uppercase
letter.
I'm still in favour of a new product, or reusing KDESupport, or even
Extragear libs. If you must use a suffix though, please consider using
Qt5, not -qt5, so that the lib becomes libSomeThingQt5, not
libSomeThing-qt5.
