[CMake] external library dependencies

Hi, nobody responded.  I have another question (see below).

If I had the full path to the library, is the modified time  
dependency noted then?

FIND_LIBRARY(MY_LIB mylib ...)
TARGET_LINK_LIBRARY(mainLib ${MY_LIB})

Is it possible to add a file dependency to a target like you can to a  
source file (ala SET_SOURCE_FILES_PROPERTIES(... PROPERTIES  
OBJECT_DEPENDS ...) )?
