VS 2013 can't find lib file from Boost toolkit

I'm working from the "Boost Getting Started on Windows" guide. I'm running the code:

#include <boost/regex.hpp>
#include <iostream>
#include <string>

int main()
{
    std::string line;
    boost::regex pat("^Subject: (Re: |Aw: )*(.*)");

    while (std::cin)
    {
        std::getline(std::cin, line);
        boost::smatch matches;
        if (boost::regex_match(line, matches, pat))
            std::cout << matches[2] << std::endl;
    }
}

I get the error message:

Error   1   error LNK1104: cannot open file 'libboost_regex-vc120-mt-gd-1_55.lib'   C:\local\boost_1_55_0\example\example\LINK  example

Well, of COURSE it can't open the file: libboost_regex-vc120-mt-gd-1_55.lib because the name of the binary is libboost_regex-vc100-mt-gd-1_55.lib

I added the additional link directory, but it's not looking for the right file. How can I tell it to look for the right file? BTW, using VS Express 2013, windows 7.
