Linker Error - FbxSystemUnit::m unresolved external symbol

[bdefnet]

Been using the FBX SDK for a couple of weeks now.  Making good progress.  Able to load and parse files.  Today I tried using the FbxSystemUnit::m.ConvertScene() for the first time and I'm getting linker errors.  Has anyone else encountered this or know what's wrong?

my code:

FbxSystemUnit::m.ConvertScene(m_pFbxScene);

linker errors:
