I've built yamlcpp static (libyaml-cpp.a) library using Qt's mingw compiler. Now I want to add it to my project. I use this qt doc, but Qt Creator allows to select only *.lib files not *.a files (in Choose file dialog). That's confusing because I'm using MinGW 4.4 debug configuration, not MSVC2008.

Is it possible to add *.a libraries via Qt Creator's GUI and how do I do it?

Windows 7, Qt Creator 2.3.1, Qt 4.7.4
