The imported targets are new.  Looks like a small glitch...

Here are the docs:
http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:IMPORTED_LOCATION
http://www.cmake.org/cmake/help/cmake2.6docs.html#prop_tgt:IMPORTED_IMPLIB

Looks like IMPORTED_LOCATION should be ignored if IMPORTED_IMPLIB is found.

You can export symbols from an executable on windows.  So, CMake will 
create the import library file.
