I have been following instructions to use a json lib with qt;
http://qjson.sourceforge.net/download.html

I have followed the instructions and got a "libqjson.dll" and a "libqjson.dll.a" out of it.
But I'm not sure what to do with these.
I tried putting these in the "\Qt\2009.04\lib\qtcreator\plugins\Nokia" directory, but it didnt show up in the Plugins About box.
What should I do?
