title: Preprocessor directives from C++ code (_VARIADIC_MAX)
body: <p>Please how to define preprocessor directive _VARIADIC_MAX=10 from C++ code? For now I set it in Property Page -> C/C++ -> Preprocessor -> Definitions but I need it in each project. Will be cool to define it one time in some common.h file and use in every project by including such header.</p>
