qt5quick1 includes the old libs, interpreter, modules, etc. It is probably provided to 
ease porting from Qt 4.x. So it has no dependency on qt5declarative.

QML is the name of the language. Quick is the name of QML module kit that is used to 
create user interfaces. qt5declarative contains both the interpreter and Quick module 
kit. It seems possible to use QML without Quick.

QML files in the other qt5* modules depend on Quick modules. Those are not built 
when quick is disabled.
