The chapter about kdevelop and templates is for tomorrow.
I've already found out that this kind of fun isn't entirely new. However, I couldn't find a solution that works here.

Any ideas anybody?

Nobody? Seriously?
There's this other thread where something with kdevelop's handling of environment variables went wrong. That happens here too. But it's not why cmake won't find any qt includes. I'll probably go with manually written Makefile or qmake. But I don't think this is a cmake bug (and I didn't find one filed.). It must be some PEBKAC that I don't see.

yelp!

Well, at far as I can see, it finds Qt5. But you are trying to compile a KDE4 application which needs Qt4.

So, do you have the necessary qt4 devel packages installed?
Probably there is a conflict, so maybe try to remove the Qt5 ones as well.

I have no experience with Ubuntu though, sorry. You might want to ask in a distribution-specific forum.

Unfortunately the forum isn't too great with development questions i'm afraid. Most developers still tend to prefer mailing lists.
In terms of your problem here - you need to install the appropriate Qt 4 development package (libqt4-dev I think) to continue.
