When a library which implicit library dependencies is linked, the libraries it depends on to successfully link are automatically added by the linker, but are not additionally recorded as dependencies. The implicit dependencies (and explicit dependencies) are again used when the program is started by ld.so. Using implicit library dependencies successfully is actually a bit of work but it is very useful to OS distributions which want to update libraries (or groups of libraries) via a package manager without needing to update dependent applications or libraries. The normal libtool operation is to record all of the involved libraries as dependencies since they are all added to the link line.
