yii import extension not finding class

问题

I am using the Facebook SDK For PHP. I added the facebook php SDk in the yii app protected/extension folder and imported it in config/main.php as follow.

'import' => array(
    'application.extensions.facebook.*',
),

my problem is that the app is not finding the classes in the sdk when i create the object as follows:

 $session = new FacebookSession($access_token);

it is giving error as follow:

Fatal error: Class 'FacebookSession' not found ....

if I try using include_once() or require_once() then it is giving error as below:

Fatal error: Cannot redeclare class Facebook\FacebookSession in D:\localhost\protected\extensions\facebook\FacebookSession.php on line 36

What is going wrong?

Solved this by adding

set_include_path(Yii::app()->baseUrl . DIRECTORY_SEPARATOR . 'protected' . DIRECTORY_SEPARATOR . 'extensions' . DIRECTORY_SEPARATOR . 'facebook');

require_once (Yii::app()->baseUrl . DIRECTORY_SEPARATOR . 'protected' . DIRECTORY_SEPARATOR . 'extensions' . DIRECTORY_SEPARATOR . 'facebook' . DIRECTORY_SEPARATOR . 'autoload.php');

require_once (Yii::app()->baseUrl . DIRECTORY_SEPARATOR . 'protected' . DIRECTORY_SEPARATOR . 'extensions' . DIRECTORY_SEPARATOR . 'facebook' . DIRECTORY_SEPARATOR . 'src' . DIRECTORY_SEPARATOR . 'Facebook' . DIRECTORY_SEPARATOR . 'FacebookSession.php');

and for creating object

$session = new Facebook\FacebookSession($access_token);
