Latency Manager from GRCON2019

[Fabien PELLET]

Hello,

I'm trying to compile the project OOT of latency manager of Matt ETTUS 
from he presents at the GRCON2019.

For that I built from source GNURadio to get 3.9 version successfully 
but I can't compile the project provided here : 
https://github.com/dkozel/gr-workinprogress.

The CMAKE fails and tell that it can't find GRSwig. I'm on Ubuntu 20.04.

Thanks for any help or suggestions.

Best regards,

Fabien PELLET, F4CTZ.
