But how can I combine branch name together with commit? I've already specified branch "2.0" as QSERIALDEVICE_VERSION.

O.K. I thought there would be some kind of elegant and easy way, like an option that copies only symlink and not it's target if desired :-)

You won't believe me, but it worked without cd statement. That's why I was puzzled by my local package not willing to create Makefile in output/build/vsguitest. But I fix it for QSerialDevice for conformance sake.

It requires both build-time and run-time udev. This package provides two classes/interfaces:
1. serial port itself
2. informational class containing all installed serial port sin the system and it uses libudev (I'll send a patch that installs udev in staging)
