In OpenObex, we use additionally a .def file with exports. "obex.sym" is a list 
of symbol names (one per line) and is also used by libtool:

if ( MSVC )\r
  set ( OPENOBEX_DEF_FILE "${CMAKE_CURRENT_BINARY_DIR}/openobex.def" )
  file ( WRITE "${OPENOBEX_DEF_FILE}"
        "VERSION ${openobex_VERSION_MAJOR}.${openobex_VERSION_MINOR}\n"
       )
  file ( APPEND "${OPENOBEX_DEF_FILE}" "EXPORTS\n" )
  file ( READ "${CMAKE_CURRENT_SOURCE_DIR}/obex.sym" OPENOBEX_SYMBOLS )
  file ( APPEND "${OPENOBEX_DEF_FILE}" "${OPENOBEX_SYMBOLS}\n" )
endif ( MSVC )

You have to use this to get sensible symbol names that you can use from 
language bindings when using WINAPI.

OTOH, it should be sufficient to add a link to the right VisualStudio 
documentation. Almost everything regarding windows DLLs with msvc is described 
there, and lots better than what gcc provides as documentation (mostly 
cryptic).
