+      "The INCLUDES DESTINATION specifies a list of directories which will "
+      "be added to the INTERFACE_INCLUDE_DIRECTORIES of the <targets> when "
+      "exported by install(EXPORT).  If a relative path is specified, it is "
+      "treated as relative to the $<INSTALL_PREFIX>.  "

Should the "INCLUDES DESTINATION" option produce an error if it is
used without the EXPORT option?

Also, note there are two trailing spaces at the end of the paragraph.
