what are the first things i need to do?
1. Read the API documentation for drivers and device.
2. Read about ActiveQt. OPOS is a COM (ActiveX) interface to point-of-sale devices.

How I can add the reference or library in qt.?
I assume you mean "reference" in the Visual Basic sense, meaning "semi-transparent linkage to an ActiveX control." In that sense there is no equivalent for a compiled C++ program (note that is not a Qt thing). ActiveX objects are accessed using ActiveQt or the just the Windows COM API in Qt C++ programs.

You link a library with your Qt C++ program using the LIBS variable in your PRO file. An ActiveX object is not a library in this sense.
