That probably won't work for Cygwin.  The engines are linked against the
versioned DLLs of the OpenSSL version they have been built for,  Even
assuming binary compatibility, an engine linked against openssl-1.0 will
pull in openssl-1.0 DLLs, even when loaded from openssl-1.1.  We have to
keep the engines separate.
