Good idea.

Please, consider the following feature:

    * If the optional package was not found, there should be explicit WARNing 
in the summary section at the end.

Motivation:

    The lack of an optional package is often left unnoticed in the 'configure' 
output. As a consequence, the main package is either functionally restricted, or 
built with bundled optional package, or <...>.

    When a lack of optional package seriously degrades the main package, the 
user should be properly notified.
