The default is to use the system lib if it's present and fallback to the
bundled copy if not. If you want to force the system lib, force the bundled
copy or force the option to be disabled, you need to pass an extra option.
I don't think -use-system-libs is useful for you because you *still* need to
pass the option to ensure that the feature gets enabled:
That is
-sqlite
sqlite systemwide: uses systemwide
sqlite missing: uses bundled copy
-sqlite -use-system-libs
sqlite sysstemwide: uses systemwide
sqlite missing: disables sqlite plugin
-system-sqlite:
sqlite systemwide: uses systemwide
sqlite missing: configure fails
