In fact, it is supposed to use by default the system version and use the
private version only if no system version can be found.
This means that the detection of the library is broken on MacOS.

I think the reason we keep a private copy of the library is that it was
easier for the user to compile digikam. I guess that when lqr will be
properly packaged in all main distributions and that the detection of the
library works properly the private version of library will be removed from

The gimp lqr plugin is more complicated to use than Digikam's one, it is
adapted to the philisophy of gimp using layers, but not everyone wants to
