[Digikam-users] svn build fails: testlensiface has undefined reference to lkdecore

[sean darcy]

Today's svn fails as below. AFAICS this is because Fedora no longer 
permits implicit linking. See:
https://fedoraproject.org/wiki/UnderstandingDSOLinkChange

How do I set up libkdecore as an explicit link?

BTW, I tried posting this on the dev mailing list, but it disappeared 
into the ether. So if you're seeing it twice, I apologize.
