I don't think that has ever been implemented...   The imported targets 
are a very different thing than the included external projects.    You 
might also be able to use imported targets and the external include 
together to get this to work...   You would have to create an "imported" 
target for the libraries that are built in your external project.  Say, 
you had an external pojrect foo.vcproj that built bar.lib.  You would do 
something like this:
include_external_msproject(externalms bar.vcproj)
  add_library(bar SHARED IMPORTED)
  set_property(TARGET bar PROPERTY IMPORTED_LOCATION c:/path/to/bar.dll)
  set_property(TARGET bar PROPERTY IMPORTED_IMPLIB c:/path/to/bar.lib)

Then link to bar in the CMake code. Then the MAP_IMPORTED should work. 
You will want to make sure that externalms depends on all the targets 
that use bar.
