 We prefer to have both an explicit enable and disable (or with and without)
because:

- it makes it simpler in case the default changes after a version bump;

- it makes it easier for other people to understand that the right thing is done
(no need to check in configure what the default is);

- AFAIK the typical --enable/--with will give an error if the dependency is not
found, which gives an extra safety net;

- we do it like this in other places, it's nice to see the same pattern everywhere.


 Regards,
 Arnout
