[Interest] Getting QSerialBus from Git

[André Hartmann]

Hi List,

I've followed the instructions from

  https://wiki.qt.io/Building_Qt_5_from_Git

to get a recent snapshot of the Qt sources including QSerialBus.

Unfortunately, a directory qtserialbus is created, but stays empty (I've 
tried branches 5.6 and dev).

What do I have to do to get the QSerialBus module?

Best regards,
Andre
