I don't exactly like the Qt5 dependency.

While not being a problem per se it makes the build-dependency footprint of
stuff only using the non-Qt parts bigger than needed.

So far this was no issue since

# grep-dctrl -FDepends gpgmepp -sPackage /var/lib/apt/lists/httpredir.debian.org_debian_dists_unstable_main_binary-amd64_Packages
Package: libgpgmepp-dev
Package: libqgpgme7
Package: libkf5gpgmepp-dev
Package: libkf5qgpgme5
Package: kaddressbook
Package: kmail
Package: libkf5messagecomposer5
Package: libkf5messageviewer5
Package: kleopatra
Package: libkf5wallet-bin
Package: libkwalletbackend5-5
Package: libkf5libkleo-dev
Package: libkf5libkleo5

(only KDE5 stuff using Qt5 anyways.)

but starting from LibreOffice 5.4 we have libreoffice-core having a
build-dependency on libgpgmepp-dev and LibreOffice (still, yes, I consider
that a bug, but..) uses Qt4/KDE for -kde, not Qt5.

Can the qgpgme(pp) stuff split out to an own -dev (As was already done
with the library itself.) and only that one be made depedant on libqgpgme7?
( This would probably require a transition and the above apps changing their
Build-Depends:, but..)

Regards,

Rene
