Actually, this warning is GDAL specific, and has nothing to do with curl (but
of course curl without SSL support is rather useless). The service account
authentication method of Google OAuth2 requires using a RSA signing key to
create signed requests to GCS, and, for that, "GDAL must be built against
libcrypto++ or libcrypto (openssl)" (sorry, can't find a better wording :-))

$ ./configure --help | grep crypto
  --with-cryptopp=ARG       Include cryptopp support (ARG=yes, no or path)
  --with-crypto=ARG       Include crypto (from openssl) support (ARG=yes, no
or path)
