Linking TagLib to my Qt app on Windows?

I compiled taglib.dll using there instructions: http://www.joelverhagen.com/blog/2010/11/how-to-compile-taglib-on-windows/

I now try to link it with my application using the following options: win32:LIBS += -L"./resources/win" -ltag

ld.exe fails saying -ltag cannot be found. I've tried this with -L"C:/absolute/path" -ltag and a number of other ways but always the same. The taglib.dl开发者_高级运维l file is located in ./resources/win/... What am I doing wrong?
