That would sent the wrong message in the TLDR, as the step-by-step guide
and the reference section would be the first place to look for details,
which is kinda implicit for a TLDR.

That being said: that made me look closer at the install section of the
guide and the reference section. I think they should mention "consult
documentation of your distribution" more clearly. I just looked into
this, but that requires a few bigger changes, so I'll take care of that
in a later patch I hope to send in the next few days.

Well, yes, that's why the patch also added a few lines to point this out
and mention that installing the qt dev headers is optional. Guess you
just missed that.

Ciao, Thorsten
