    <para>
      The <application>CMake</application> package contains a modern
      toolset used for generating Makefiles. It is a successor of the
      auto-generated <command>configure</command> script and aims to
      be platform- and compiler-independent. A significant user of
      <application>CMake</application> is <application>KDE</application>
      since version 4.

      If you want to investigate a problem with a given "problem1-test",
      use <command>bin/ctest -R "problem1-test"</command> and, to omit it, use

      Option <option>-N</option> can be used to display all
      available tests, and you can run <command>bin/ctest</command> for a
      sub-set of tests by using separated by spaces names or numbers as
      options. Option <option>--help</option> can be used to show all options.

    <para>
      <command>sed ... Modules/GNUInstallDirs.cmake</command>:
      This command disables applications using cmake from attempting to
      install files in /usr/lib64/.
    </para>

    <para>
      <parameter>--system-libs</parameter>: This switch forces the build system
      to link against <application>Zlib</application>,
      <application>Bzip2</application>, <application>cURL</application>,
      <application>nghttp2</application>,
      <application>Expat</application> and <application>libarchive</application>
      installed on the system.
    </para>

    <para>
      <parameter>--no-system-jsoncpp</parameter> and
      <parameter>--no-system-cppdap</parameter>: These switches remove the
      <application>JSON-C++</application> library from the list of system
      libraries. A bundled version of that library is used instead.
    </para>

    <para>
      <parameter>--no-system-librhash</parameter>: This switch removes the
      <application>librhash</application> library from the list of system
      libraries used. A bundled version of that library is used instead.
    </para>

    <para>
      <option>--no-system-{curl,libarchive,libuv,nghttp2}</option>: Use
      the corresponding option in the list for the
      <command>bootstrap</command> if one of the recommended dependencies is
      not installed. A bundled version of the dependency will be used instead.
    </para>

    <para>
      <option>--qt-gui</option>: This switch enables building the
      <application>Qt</application>-based  GUI for
      <application>CMake</application>.
    </para>

    <para>
      <option>--parallel=</option>: This switch enables performing the

      at one time.
