+# ECMGenerateDBusServiceFile
+# ---------------------------
+#
+# This module provides the ``ecm_generate_dbus_service_file`` function for
+# generating and installing a D-Bus service file.
+#
+# ::
+#
+#   ecm_generate_dbus_service_file(
+#       NAME <service name>
+#       EXECUTABLE <executable>
+#       [SYSTEMD_SERVICE <systemd service>]
+#       DESTINATION <install_path>
+#   )
+#
+# A D-Bus service file ``<service name>.service` will will be generated and installed
+# in the relevant D-Bus config location.
+#
+# ``<executable>`` must be an absolute path to the service executable. When using it with
+# ``KDEInstallDirs` it needs to be the ``_FULL_`` variant.
+#
+# On Windows, only the file name of ``<executable>`` is used since D-Bus service executables
+# are to be installed in the same directory as the D-Bus daemon.
+#
+# Optionally, a ``<systemd service>`` can be specified to let systemd consider the corresponding
+# systemd service initialized once the D-Bus name has been acquired by the executable.
+#
+# Example usage:
+#
+# .. code-block:: cmake
+#
+#   ecm_generate_dbus_service_file(
+#       NAME org.kde.kded5
+#       EXECUTABLE ${KDE_INSTALL_FULL_BINDIR}/kded5
+#       DESTINATION ${KDE_INSTALL_DBUSSERVICEDIR}
+#   )
+#
+# .. code-block:: cmake
+#
+#   ecm_generate_dbus_service_file(
+#       NAME org.kde.kded5
+#       EXECUTABLE ${KDE_INSTALL_FULL_BINDIR}/kded5
+#       SYSTEMD_SERVICE plasma-kded.service
+#       DESTINATION ${KDE_INSTALL_DBUSSERVICEDIR}
+#   )
+#
+# Since 5.71.0.
