You're going to have a really hard time with this sort of thing in
general.  Have you considered building the application in an 18.04
chroot or container, which should be entirely possible even if the host
system is running 16.04?  It's going to be much easier to get that sort
of thing working reliably than to cobble together the sort of thing
you're trying.
