You expect this is creating a tuple (or so I see from your "in" test in
the following code), but in fact the parenthesis do *not* make a tuple. 
If you look at ignored_dirs, you'll find it's just a string.  It's the
presence of commas that signam a tuple.  You need

ignored_dirs = (
    r".\boost\include",  # It's that comma that makes this a tuple.
    )
