    Automatically use OpenSSL by default on UNIX if it is available
    
    Since https is almost ubiquitous nowadays we should support it by
    default whenever possible.  When building our own curl, we already
    automatically enable SSL/TLS support on Windows and OS X by using the
    OS-native APIs.  On UNIX platforms we need to use OpenSSL but have not
    done so by default before, leading to possible user confusion when https
    transfers fail later.  Fix this by searching for OpenSSL quietly and
    enabling use of it automatically if it is found.

+enable-ssl-automatically
+------------------------
+
+* On UNIX platforms, when building CMake itself from source and not using a
+  system-provided libcurl, OpenSSL is now used by default if it is found on
+  the system.  This enables SSL/TLS support for commands supporting network
+  communication via ``https``, such as :command:`file(DOWNLOAD)`,
+  :command:`file(UPLOAD)`, and :command:`ctest_submit`.
