The DLL is a special purpose FIPS DLL. It is missing most general classes. It only has classes for FIPS algorithms. You still have to link to cryptlib.lib to get the missing classes. Also see https://www.cryptopp.com/wiki/FIPS_DLL. You should link to the static library. _IF_ you really want a DLL then create a wrapper DLL than links to the static library. I want to delete the projects because (1) the DLL is on the Historical Validation List so it is no longer valid; and (2) it is a constant source of problems for users.
