You need to use a sentinel file:

        all: .config-sentinel

        .config-sentinel: config.ini
                pack.exe -f $< -v
                @touch $@

Now whenever the config file is compiled, the sentinel file
(.config-sentinel) is updated.

This is not perfect (for example, if someone deletes one of the output
files like "data.pack" make won't realize that it needs to run the rule)
but it basically works.  To get any more accurate you'll have to have a
way of generating a list of files that pack.exe will generate (or has
generated) and then turning that into make prerequisite statements.
