Comment (by NicosPavlov):

 This is because exiv2 moved the version information from one file to
 another, breaking the FindExiv2.cmake file (provided by kdelibs4). This
 can be fixed in kdelibs4 with the attached patch.

 There are however other problems, as there have been some changes in the
 API of Exiv2 version 0.27, so that libkexiv2 does not build regardless of
 finding the library.
