PhpWord running problem - no such file PhpWord.php

I try to run PhpWord on server but have issue.

autoload.php

<?php
function loadLibraries($class) {
    $path = __DIR__.'/lib/';
    require_once $path.$class.".php";
}

spl_autoload_register("loadLibraries");

?>

and here is my PHP script

zml.php

<?php
error_reporting(E_ALL);

require "autoload.php";


// Create a new PHPWord object

use \PhpOffice\PhpWord\PhpWord;

$phpWord = new PhpWord();

// Add a section to the document
$section = $phpWord->addSection();

// Add some text to the section
$section->addText('Hello, World!');

// Save the document
$filename = 'hello_world.docx';
$phpWord->save($filename);

echo "Word document '$filename' has been created.";

?>

Here is error:

Warning: require_once(/zmluvy/lib/PhpOffice\PhpWord\PhpWord.php): failed to open stream: No such file or directory in /zmluvy/autoload.php on line 4
