Add an option to dependencies called 'method'. This can be used to

configure a detection method, for those types of dependencies that have
more than one means of detection.

The default detection methods are unchanged if 'method' is not
specified, and all dependencies support the method 'auto', which is the
same as not specifying a method.

The dependencies which do support multiple detection methods
additionally support other values, depending on the dependency.
