[Kde-bindings] Getting qtruby 3 for qt5 to compile

[Sylvain Joyeux]

Hi.

I've contacted Richard a month ago or so to ask about the state of
qtruby3 for qt5. In the discussion, he suggested that I could help
with the build system. It took a while for me to start on it, but here
I am.

And of course, I am having trouble. CMake troubles, I could handle
right away. Unfortunately, smokeqt compilation currently fails for me
with http://pastebin.com/4TRSPDpa.

As I told Richard, I don't mind tracking the error myself. Just need
someone to point me to the place of the most likely sources ;-) High
level information would already be nice.
