Is it possible to construct a string pattern from a list of strings?

With[{patLst = {"abc", "bcd"}, str = "zabc"},
    StringMatchQ[
        str,
        ___~~("abc" | "bcd")~~__ (* How can I construct this dynamically from patLst? *)
    ]
]

Thanks in advance.

Alternatives @@ pathLst. You can always use FullForm on that you want to get and, well do this. – Kuba Oct 05 '15 at 07:14

I have no problem with the question being marked as a duplicate. But, just for the record, I was aware of Apply but not of Alternatives. It was the latter that was holding me up. – Shredderroy Oct 05 '15 at 07:43
I see, well you may be right about that it is not the best candidate. Will come back later, don't have time to search better but there definitely is one. – Kuba Oct 05 '15 at 07:50
