Marcel,

Not with current code from git, where i copied files from OpenCV to
libkface, to turn around a big problem under windows, where it's not
possible to locate haar files at run-time if digiKam is relocated at
install (in setup you can change standard install dir). 2.0.0 is fixed
like this, not RC.

With this solution, also, haar files must be always found...

Look here for details :
