Binding TagLib to my Qt application on Windows?

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

Now I will try to associate it with my application using the following parameters: win32: LIBS + = -L "./resources/win" -ltag

ld.exe does not work if -ltag cannot be found. I tried this with -L "C: / absolute / path" -ltag and a number of other ways, but always the same. The taglib.dll file is located in. / resources / win / ... What am I doing wrong?
