Then it's not installed. In the same directory as LocalSettings.php, there should be a directory named "extensions". Put the Cite directory inside that extensions directory and make sure to install the extension as specified on the extension's page.

All the extensions you're using should be placed in that extensions directory, unless explicitly stated otherwise in the installation instructions.
