Fix linker GUARD option (#11492)
Fix linker GUARD option (#11492)

I have found that the /GUARD:CF option set in the root CMakeFiles.txt
was not being propagated to the Visual C++ project files generated
by cmake because of a wrong casing. The CMakeFiles.txt used /guard:cf
but it works correctly only if it is all upper case.
