Currently, there is not. 

It does seem that the linker can not add paths to the link line:

http://www.digitalmars.com/d/archives/c++/command-line/639.html

I am not even sure we always have that information.  For example,
someone might do LINK_DIRECTORIES(....) LINK_LIBRARIES(A). 
  
Maybe we could set the LIB env as part of the link command.
Then use the /SCANLIB option.   Then do something like this:

In Windows-bmc.cmake try this:

SET(CMAKE_LIBRARY_PATH_FLAG ";")
SET(CMAKE_CXX_CREATE_SHARED_LIBRARY 
  "set LIB=<LINK_LIBRARIES>"
  "link ${CMAKE_CL_NOLOGO} ${CMAKE_START_TEMP_FILE} /out:<TARGET> /PDB:<TARGET_PDB> /dll  <LINK_FLAGS> <OBJECTS> <LINK_LIBRARIES> ${CMAKE_END_TEMP_FILE}")

We might need to create a <LINK_DIRECTORIES> that would only have the link directories
part of the link line, but that might work with the extra junk at the end of the lib path.
