Laravel connect to Azure SQL Data warehouse using PDO

I am using Laravel 5 and want to connect to a Azure Data warehouse using the implemented PDO database connection Laravel provides. I am using the following connection settings.

DB_CONNECTION=sqlsrv
DB_HOST=tcp:srv.url.com,1433
DB_DATABASE=db-name
DB_USERNAME=user
DB_PASSWORD=pass

When I load the page I get a "could not find driver" error.

How is this possible? The drivers are build into Laravel rigth?

Thanks in advance!
