I added the proposed patch in
https://github.com/Exiv2/exiv2/issues/363#issuecomment-512774682, that
will explain that there is a known issue with building with DEBUG.
Probably not really relevant for debian, as there is a controlled build
environment. The proper solution would probably be to separately package
adobe's xmp sdk (libexempi might ship it too).
