How to import vendor files in CakePHP 3x

Question

I'm working with CakePHP 3(beta 2) version recently launched. I need to integrate Facebook Login using PHP SDKs and I'm not clear with importing vendor files in this version.
In CakePHP 2x, I had used

App::import('Vendor', 'Facebook', array('file' => 'Facebook' . DS . 'src'. DS. 'facebook.php'));

So I need to reproduce the same in CakePHP 3x(I'm not using composer).
Any reference for this?

Well you will have to load it yourself if composer is not an option. You can always use the very basic require method and create a new instance of the vendor class yourself. Reference: http://book.cakephp.org/3.0/en/core-libraries/app.html#loading-vendor-files

Use:

 //The following line should do the same like App::import() in the older version of cakePHP
 require_once(ROOT . 'vendor' . DS  . 'Facebook' . DS . 'src' . DS . 'facebook.php');

 $facebookApi = new facebook();
