This review is for the newest versions at the time:
Thunderbird 38.3.0
Lightning 4.0.3.1
Provider for google calendar 1.0.4
The setup was very straightforward. (you have to have the Provider addon installed and enabled)
File->New->Calendar->Network Calendar->Enter gmail address->Enter gmail password->Choose Calendars to sync

That was it, you are ready to go.
Avoid older instructions in thunderbird support using xml instructions and such, it is not needed.
