This is rather offtopic for this mailing list because it's not a
question about usage of make, it's a question about how to use the
compiler/linker.  The fact that you're using a Makefile is just
incidental.

In order for the dynamic linker to be able to find the .so file at
runtime, you either need to use -rpath / -R when linking, or set
LD_LIBRARY_PATH.  The former is the preferred way.  Google for details.
