Log Message:	- The --enable-openssl, --enable-gnutls switches, and their disabling counterparts --disable-openssl and --disable-gnutls, have been replaced with the --with-tls switch which takes one of the following options: 'openssl', 'wolfssl', 'gnutls', and 'none'. If nothing has been specified, configure tries to autodetect in the following order openssl/libressl -> gnutls -> wolfssl.
