+# Helper function for packaging subprojects using CommonCPack.
+#
+# Add subproject dependencies to the current project's package:
+#   add_deb_depends(<Subproject>
+#     [PACKAGE_NAME <subproject_package_name>]
+#     [MIN_VERSION <subproject_min_version>] [<subproject_deb_depends>])
+#
+# Arguments:
+# * Subproject: name of the subproject
+# * PACKAGE_NAME: if subproject package name differs from lower_case(Subproject)
+# * MIN_VERSION: minimum version of the subproject's package
+# * ARGN: list of dependencies of the subproject
+#
+# Output (list append):
+# * NAME_PACKAGE_REPLACES: Subproject package name if it is being built
+# * NAME_PACKAGE_DEB_DEPENDS: the list of Subproject's dependencies if it is
+#   being built; otherwise its package name.
