fix(build): query correct property for interface libraries

Browse Source 
431ee5c058 has changed the way ldgen works by introducing the
recursive lookup of component libraries reachable from the executable.
The implementation incorrectly queried LINK_LIBRARIES instead of the
INTERFACE_LINK_LIBRARIES property for INTERFACE targets.
