To link to the library you'd add the library to a variable called LIBS (http://doc.trolltech.com/4.4/qmake-variable-reference.html#libs). To be able to include header files of the library, you might also want to add suitable path to a variable called INCLUDEPATH (http://doc.trolltech.com/4.4/qmake-variable-reference.html#includepath).
