Find full path of a shared library.
Searches for the full path of a shared library. On Posix operating systems

Parameter
---------
name : str
Link name of library, e.g., cublas for libcublas.so.*.
Returns
-------
path : str
Full path to library.
Notes
-----
Code adapted from ctypes.util module. Doesn't check whether the
