You will either need to set up the DT_RUNPATH section in the executable
to point to where the library is installed or set up the LD_LIBRARY_PATH
environment variable to include the correct location.  The first option
requires to edit the linker invocation in the makefile, while the latter
is best done via a wrapper script that then calls the executable.

Try 'ldd -v', if that also doesn't show anything, then most likely the
program itself dynamically loads new libraries at runtime (probably
after a fork).  Setting LD_TRACE_LOADED_OBJECTS (preferrably in a
wrapper script) to something non-empty should then give some ldd-like
output.
