 Crypt::OpenSSL::Guess provides helpers to guess OpenSSL include path on any platforms.
 
-Often MacOS's homebrew OpenSSL cause a problem on installation due to include path is not added.

 Some CPAN module provides to modify include path with configure-args, but L<Carton> or L<Module::CPANfile>
 is not supported to pass configure-args to each modules. Crypt::OpenSSL::* modules should use it on your L<Makefile.PL>.
