[CMake] After working for a well over a year my cmake has suddenly stopped working, CMake Gui now fails to configure any project with the error..

[Bill Hoffman]

In the build trees, is there any more information in 
CMakeFiles/CMakeOutput.log or CMakeFiles/CMakeError.log?

Is your VS able to build things without CMake?
