Include a Local Perl Module that References a Local C Library

I want to include a local module in a Perl script that's not installed. The code below seems to work for that purpose. However, the module I want to include is a wrapper for a C library. I do it as follows:

use FindBin;
use lib "$FindBin::Bin/gray-tree-suffix-59e1c06/lib";
use Tree::Suffix;

The Perl module is called Tree::Suffix and acts as a wrapper for libstree. My question is, how do I reference the C library locally as well (given that it's not installed).

I presume it would have something to do with the inner workings of the Perl module? I apologise if this is an amateurish question. Thank you!

Have you tried this :

say the .so file is foo.so, and its full path is /bar/baz/foo.so:

BEGIN
{
  $ENV{LD_LIBRARY_PATH} = '/bar/baz:'.$ENV{LD_LIBRARY_PATH};
}

use FindBin;
use lib "$FindBin::Bin/gray-tree-suffix-59e1c06/lib";
use Tree::Suffix;

or, alternatively, change the shell's LD_LIBRARY_PATH before your Perl program is called :

export LD_LIBRARY_PATH=/bar/baz:$LD_LIBRARY_PATH
[run your program]
