Build under ubuntu 19.04 DISCO

Thank you all for making my life easier. Can’t wait to see what’s changed in the last 6 months.

EDIT: I don’t know if I should post as a bug or just warn the other couple of Ubuntu users. Closing via the quit menu option in ubuntu 19.04 (Mate w/ Studio) causes a core dump. After the core dump, I have to restart before I can run SPI again. Make sure to close via the window “X” to avoid this behavior.
