So true.

The logic of an AppImage is that you build on an OLD distro so that the glibc
that you link against is an old one and the binaries run on as many distros as
possible. We are building against CentOS 6 right now and the newest Qt that
I can get for that is 5.6. 

My guess is that I should just build Qt 5.9.1 from source and be done with it.
But I'm not sure that I can get a new enough compiler for CentOS 6 in order 
to do that.

BTW, Lubomir, which Linux distro do you usually work with?
