how to get a .lib file instead of a .dll?

I’m trying to learn how to compile a shared library(http://qt-project.org/wiki/How_to_create_a_library_with_Qt_and_use_it_in_an_application) in windows but it seems that it only outputs .dll files. I want a .lib file. Can I ask Qt creator to do that? Qt creator 2.7 Qt 5.0.1 MinGW
