Subject: [PATCH] Revert "Exiv2 is now released with exported targets using
cmake rules. No need to have a dedicated find exiv2 cmake script. Bump
minimal version to 0.27.1"
This reverts commit 06e77271d72fe5e4abeb38641f3addc2cfbff126.
Fixes build on Leap 15.x which only have exiv2 0.26.
As there haven't been any changes other than to rely on the new cmake
files in exiv2 0.27, there should be no problems with the older version.
