Excuse me to shared and maintained this library. If this not enough...

Ah, which one exactly ?

We take a care about BC and KDE release plan.

Not totally true. There is a flag in digiKam SC root cmake file to
exclude libkipi, libkexiv2, and libkdcraw of compilation and use
system based libs. This one is used by packagers.

If to include libkface in kdegraphics/libs is too problematic (as i
suspect), we can do better for KF5 : drop libkexiv2, libkipi, and
libkdcraw from kdegraphics and that all. Like this, you can be sure
that all will be clean from my side in kdegraphic/libs...
