README.md file for QFlightInstruments states that:
The building proccess will generate a debian package, so you can deploy wherever you want.
But no deb file is generated inside QFlightInstruments path after issuing any of the standard make commands.
Also, the README.md file has a section called Make Package which tells to use make package debuild -uc -us. This command results in error in error in all forms (either running make package alone, debuild -uc -us alone, or the complete command).
