I tried for over a year now to ask FSF to make LibreDWG GPLv2 or higher but
unfortunately they are not cooperating and want to keep LibreDWG as GPLv3.
Therefor LibreCAD cannot use LibreDWg directly, which is a shame if you ask me.
The only way I can see this happing (I am not a license guru) is that we create a seperate program that uses
LibreDWG to convert data into DXF and we read that, save will be the other way around.
But IMHO this is hackish.

dxflib of RibbonSoft is under GNU General Public License version 2, LibreDWG is under GNU General Public License version 3 (or at you option any later version). How link code under two version of GPL?
GPL can't linked with non-free code but:
in GLP v2 is:
" 10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally."
