a set or unordered_set cannot be used as the order is important. maybe I'll have to rewrite it all to check whether we get any paths back for the header, and if not, just use all of the source file. suggestions welcome. if this is really too slow, we could also not filter at all and just let clang handle it internally. or we could add a hash set for checking whether we want to add it and another for the ordered list - that is probably the most efficient way to do this.
