STYLE: fix #7146, add documentation for 

CMAKE[_SYSTEM]_(LIBRARY|PROGRAM|INCLUDE|PREFIX)_PATH variables
-moved CMAKE_CROSSCOMPILING from "Variables that modify behaviour" to
"variables that Provide Information", since it should be used only for
testing whether we are currently in cross compiling mode, not for switching
between the modes.
