Maybe you can file a feature request, so that you can do 
get_target_properties(libs yourlib LINK_INTERFACE_LIBRARIES)
works if you have set LINK_INTERFACE_LIBRARIES using TARGET_LINK_LIBRARIES(... 
LINK_INTERFACE_LIBRARIES)

If you haven't done that, it returns NOTFOUND. Maybe you could file a feature 
request that get_target_property(<var> <target> LINK_INTERFACE_LIBRARIES) 
should return the full set of linked libraries (which will be the link 
interface libraries) if LINK_INTERFACE_LIBRARIES has not explicitely been 
set.

For libraries you can also have a look at the <target>_LIB_DEPENDS variable, 
maybe that helps.
