You are linking a 64-bit library to a 32-bit application. You are also linking against the release and the debug version of the same library.
So open your project settings and change the setting where you specified the library.
for debug builds and
for release builds.
Finally change your CPU type to x64 (or change the above pathes to use the 32-bit versions of the libraries).
