I am unsure we have a tool which will do exactly that.
As you tried, ldd will show the exact libraries resolution, without mentioning
the origin of the dependance.
The dependance is registered in the elf file itself, and could be shown with
readelf(1):
$ readelf -d /usr/X11R6/lib/libXrender.so.6.0 | grep '(NEEDED)'
0x0000000000000001 (NEEDED) Shared library: [libX11.so.18.0]
0x0000000000000001 (NEEDED) Shared library: [libxcb.so.4.1]
But it doesn't resolv the path.
You could try several options of ld.so(8) which is using environment variables
(look at the man page for full list):
here, using LD_DEBUG and keeping only the 'loading' lines:
