Ah thanks for the answer.

Yes, I'm pretty sure I have -DENABLE_QT5=ON, though I use ccmake. I also
tried cmake now (see below for full command + output used).

But crux indeed is that for qca and libqwt, that apparently not have
install candidates in a clean Debian Stable. See below for current
status of those in different Debians.

Next try will then be on compiling on Debian testing...
Not sure if Bas knows if there is a chance that those qt5 version will
come into Jessie. But I understand Jurgen also has been busy to create
packages for the time (Qt4-)Webkit is removed from repo's. So for normal
installation there is a solution too.

My point is I just try to be able to compile/install/test from source on
a (if possible) vanilla Debian (be it Jessie or Wheezy is both ok for me).

So: testing/Wheezy will be next for me!

Regards & Thanks for putting time into all this,

Richard
