I did this and created a new "Program", which was labeled in Lazarus
as a Free Pascal command line program.

Then I added my units from the other project and converted the dpr
file into a pas unit by moving away the final begin-code-end proram
section to the newly created program's source file.
Had to fix sections etc in the old dpr file so it now is a proper
But once done it built OK and worked as expected in Ubuntu 18.04.
The stripped size of this program as about 10 Mb whereas the earlier
version was only some 7 Mb...

But when I copied it over into the Ubuntu 16.04 server it again
displayed the GTK error...

(LicMgr:19450): Gtk-WARNING **: cannot open display:

It should not need a display!
