svn build fails with undefined reference to libkdecore

[sean darcy]

The build fails on Fedora 13. AFAICS, the problem is that Fedora now
doesn't permit implied linking. See:

http://fedoraproject.org/wiki/UnderstandingDSOLinkChange

But how do I explicitly tell digikam to link with kdecore?

You need to add the suggested lib (kdecore) into lensfun CMakeLists. I think. I solved a few of these in digikam already (as I'm also on F13, I'll update my local copy and see what I can do about it and I'll commit a fix.

By the way, this is the 1.5.0 branch or 2.0 branch?
