Notes
(0032280) Brad King (manager) 2013-02-14 08:36	The variable gets set as documented here: http://www.cmake.org/cmake/help/v2.8.10/cmake.html#variable:CMAKE_LANG_COMPILER_LOADED [^] but it gets eaten by the function's nested variable scope. As a generalization of my comments in this thread: http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/45460 [^] the language initialization needs an overhaul to be scoped properly. Sending to backlog for now. Use a macro to work around.
