Tells curl to use the specified certificate directory to verify the
peer. Multiple paths can be provided by separating them with ":" (e.g.
"path1:path2:path3"). The certificates must be in PEM format, and if curl is
built against OpenSSL, the directory must have been processed using the
c_rehash utility supplied with OpenSSL. Using --capath can allow
OpenSSL-powered curl to make SSL-connections much more efficiently than using
--cacert if the --cacert file contains many CA certificates.

If this option is set, the default capath value will be ignored.
