Hi Robert,
I have updated the wiki page:
http://code.google.com/p/qextserialport/wiki/QextSerialPort_1_2_Beta1
"How to use (3)" discusses how to use QextSerialPort as shared library
without adding "include(*****/qextserialport.pri)" to .pro file.
And of course, in a cross platform way.
Hope this can help you.
If this is still refuse to work,feel free to report bugs.
Regards,
Debao
