Add workaround to prevent linker errors about unresolved external symbols.

 The errors were looking like this:

     jniFlyCapture2.obj : error LNK2001: unresolved external symbol "... FlyCapture2::CameraBase::GetRegisterString(...)" ...
     jniFlyCapture2.obj : error LNK2001: unresolved external symbol "... FlyCapture2::CameraBase::StartSyncCapture(...)" ...
     ...\jniFlyCapture2.dll : fatal error LNK1120: 2 unresolved externals
