Hello Michael,

Please use openembedded-devel at lists.openembedded.org for generic
questions like this, use [meta-qt5] tag (like README suggests for
sending patches).

It's correct, the reason is that not every qmake built project actually
needs to use Qt headers, so they are not included by default, see
