   Of course not - you're not including Qt, are you? If it's source
   code you wrote yourself, that happens to call Qt routines, then it
   is not subject to the Qt license.

By linking to a GPLed library, which Qt is, you must abide by that
license.

Also, the OP is _including_ GPLed source code into his library, not
just linking it.
