+* The :module:`CPackRPM` module learned a new

+#  Variable is not component based as its content can be used to set a different

+#  Only prefixes that are required by a certain component are added to that
+#  component - component must contain at least one file/directory/symbolic link
+#  with CPACK_RPM_RELOCATION_PATHS prefix for a certain relocation path
+#  to be added. Package will not contain any relocation paths if there are no
+#  files/directories/symbolic links on any of the provided prefix locations.
+#  Packages that either do not contain any relocation paths or contain
