Usually it is better to set CMAKE_PREFIX_PATH to
/opt/zimbra/openssl-1.0.0d, and then let FindOpenSSL.cmake do its work.
Without looking at FindOpenSSL.cmake, the -DOPENSSL_LIBRARIES=...
argument looks fishy to me, because usually XXX_LIBRARIES variables are
not cached, but a concatenation of various XXX_LIBRARY variables.
