Sink/Kube: 2 questions

[René J. V. Bertin]

And I keep hitting Send too soon:

Is the dependency on Kirigami a required one, and if so shouldn't there at least 
be a cmake warning when it's not available? I didn't notice the dependency and 
now have a kube-mail executable that just "hangs" with a terminal error until I 
install Kirigami

%> kube-mail 
QQmlApplicationEngine failed to load component
file:///opt/local/share/kpackage/genericqml/org.kube.components.mail/contents/ui/main.qml:22 
Type MailComponent.Mail unavailable
file:///opt/local/share/qt5/qml/org/kube/components/mail/Mail.qml:25 module 
"org.kde.kirigami" is not installed

^C

And since the subject says "2 questions" :)
Is it normal that Kube's cmake step fetches the breeze repo even if the breeze 
icons are installed (but only the light side in my case)?
