Probably you should post the error message and some more details on how you have setup the different projects. Otherwise this is crystal ball reading.

You have selected a 32 bit kit and you like to link with a 64 bit library?
This will not work. You need to stay in the memory model and probably the compiler version depending on how the interface to the lib is defined. To keep it save, I would propose also to stay with the same compiler version.
