As an aside, is 'edit' a std::string?  regex_match should be able to
deal with that directly, no need for c_str().

Is /lib in your runtime library search path?  On linux, that's
LD_LIBRARY_PATH.  Looks like it's DYLD_LIBRARY_PATH on OSX.

You might also be able to use rpath in the link step, where the link
stores the path to the library as found at link time, instead of
having dyld search for it at runtime.  I think you want:

  -Wl,-rpath

On the g++ command line.

Good luck!
