There are a number of KMM features that are optional, and selected at configure time. Currently there is no easy and complete way to know which of such options were chosen for the application the user is actually running. This was the subject of a reviewboard request https://git.reviewboard.kde.org/r/119287/ which was discarded. My understanding is that there were not any theoretical problems with the request, but there seemed to be a problem with the implementation. If so, I'd like to keep this as a potential feature, perhaps to be revisited once the Frameworks migration is complete.
