This looks like a very GNU-specific link flag, and is therefore not an 
option for CMake.

Last week we came up with a possible way to achieve this and I added a 
feature request:

http://www.cmake.org/Bug/bug.php?op=show&bugid=1790

Basically we would be able to get the list of object files associated 
with a given library and then link them into another library using the 
current external object feature.
