undefined reference Device.cc

Hi, I can't compile your code. Can you please help?

@fourpoint you seem to be missing libusb. You need these libraries: qt5 qtcharts libusb-1.0 libb6 along with their development headers if your package manager doesn't install them (on Arch you are set, on Ubuntu for example you need to run sudo apt install libusb-1.0-0-dev).

It may also be a difference in apt, as I now see that in there it's libusb-1.0-0 instead of libusb-1.0.

Hi @maciek134 ,
I'm encountering the same issue as @fourpoint . I made sure to install all the dependencies, and while libb6 installation went smoothly, the charge-guru failed at compilation. Here's my output:

@Pokornz I'll spin up a Ubuntu VM and take a look. Which version do you use?
