I found this behaviour in many ports and I agree that by
default people should be able to explicitly state what they want. On
the other hand it can be extremely convenient to get all plugins your
system supports by default (for those of us you build their ports
themselves). I solved this in this PR by adding an "AUTODETECT" option,
that allows the port to detect automatically only when explicitly asked
by the builder. I had that turned on by default to make sure
the port behaves exactly like it did before conversion to OptionsNG
(it's not my lawn, you know). The committer changed that to be off by
default, since this is a better solution for package building and I
agree with him.
Also note that there are a lot of ports that use either techniques for
auto detection (e.g. checking for the existence of libraries to bring
in functionality) and that those should be covered as well - simply not
allowing auto detection will massively reduce functionality, so using
an OPTION to allow it might be the way to go. I think AUTODETECT might
be an interesting candidate for bsd.options.mk though.
