Anton,

I have been checking your propose with octomap. It doesn't compile and 
represents to patch a lot because all the scripts, especially cmake, find qt4, 
and expects libqglviewer build against qt4. Also, I have seen that it's ready 
to find libqglviewer-qt4, instead of libqglviewer.

So, octovis (octomap source) needs qglviewer compiled against qt4. 

Another thing is that upstream release another version that could be build 
against qt5. I have made an issue to see what does upstream think about it 
[1].

I'm afraid that I'm not able to patch octovis in the next weeks to use _only_ 
qt5, so, if it's not too much work, for at least the next months, I would ask 
you that provide both versions. But, I have the opinion that we should drop 
the qt4 support in qglviewer for Stretch.

Thanks for all,

Leopold
