Qt Creator highlighting with CMake and add_compile_option preprocessor experimental

[qnope 0]

Hi :).

I am having some hjighlighting issues using Qt Creator 4.9.2.
When I use this option into my CMakeList, the highlighting does not work at all (nor the auto completion) and I don't understand why...

        add_compile_options(/experimental:preprocessor /permissive-)

Without the /experimental:preprocessor, it works perfectly well.

After some investigation, it is from clang code model...
