[development] Should google-api-php-client be a library?

[webmaster]

Hi folks,
I'm creating a new Drupal module for the connection to Google Calendar
using Google API. I know the main aim of Drupal libraries is for CSS and JS
instead of google-api-php-client is mainly a PHP library.
Do you suggest to me to put google-api-php-client files in
sites/all/libraries anyway or to ship google-api-php-client in my module?
Thanks,
Fair
