        <option>openssl</option>. This requires the
        <productname>OpenSSL</productname> package to be installed.  Building
        with this will check for the required header files and libraries to
        make sure that your <productname>OpenSSL</productname> installation is
        sufficient before proceeding.  The default for this option is auto.

        Build with support for GSSAPI authentication. MIT Kerberos is required
        to be installed for GSSAPI.  On many systems, the GSSAPI system (a part
        of the MIT Kerberos installation) is not installed in a location
        that is searched by default (e.g., <filename>/usr/include</filename>,
        <filename>/usr/lib</filename>).  In
        those cases, PostgreSQL will query <command>pkg-config</command> to
        detect the required compiler and linker options.  Defaults to auto.
        <filename>meson configure</filename> will check for the required
        header files and libraries to make sure that your GSSAPI installation
        is sufficient before proceeding.

        this requires the <productname>OpenLDAP</productname> package to be
        installed. On Windows, the default <productname>WinLDAP</productname>
        library is used.  Defaults to auto.  <filename>meson
