Fixes issues using DepsPath(32|64), was using ${lib_suffix} instead of
${_lib_suffix} so 32/64-sepcific directories wouldn't work properly.
Also the DepsPath environment/cmake variable wasn't specified for the
library search.
Also added the same dependency search paths for libfdk (if someone wants
to use it on windows for whatever reason)
