Gwenview CI failure

[Ben Cooksley]

Hi all,

For some time now (since the Baloo functionality merge) Gwenview has
failed to build on the CI system.

See http://build.kde.org/view/FAILED/job/gwenview_master/206/consoleText
 for the build log.

This appears to be due to Baloo using KFileMetaData includes, but not
properly specifying it as a dependency. This shouldn't be a problem if
*Config.cmake files and link targets are used.

Can someone please take a look?

Thanks,
Ben
