I have cloned this and the submodule to my Ubuntu system. I had build essentials, but I had to install a few extra dependencies...
sudo apt install libusb-1.0-0-dev
sudo apt install qt5-default
sudo apt install libqt5svg5-dev
However, now when I try to build, I get the following... (this is after it fails once, so the successful compilation/linking doesn't show up)

I've tried troubleshooting, but I'm not a dev. Googling for the ld errors brings up some options, but I tried all the items I found and none worked.
