      This package does not come with a test suite.

      Unlike other KF6 packages, this module is installed in /usr because
      it can be used by some non-KF6 packages.

    <title>Command Explanations</title>

    <para>
      <command>sed ... Modules/KDEInstallDirs.cmake</command>:
      This command disables applications using cmake from attempting to
      install files in a <filename class="directory">lib64</filename>
      sub-directory.
    </para>

    <para>
    <command>sed ... ECMConfig.cmake.in</command>:
      This command protects the global <application>cmake</application>
      variable <envar>PACKAGE_PREFIX_DIR</envar> from being changed when
      checking ECM presence: since we install ECM into <filename
      class="directory">/usr</filename>, the check would set that variable to
      <filename class="directory">/usr</filename>, while most KDE packages
      expect it to be set to <filename class="directory">/opt/kf5</filename>
      and would fail to build if it is set to something else.
