Options for defining preprocessor macros with parameters for entire project or solution in Visual Studio

I want some macros having parameters to be available in all files in a project or better a complete solution. In VS2010, if I add them to the Preprocessor Definitions in properties->Configuration Properties->C/C++->Preprocessor using something like

SQUARE(x)=((x)*(x));CUBE(x)=(SQUARE(x)*x);

the macro definitions are not used by the compiler. However the approach may be close since IntelliSense provides the correct definitions when I hover over the macros in the source code.

Is there a way to define the macros and make them visible without including a header with their definitions in every file?

Thanks for any ideas!

Place the macro in a file and automatically include it into all files using the /FI option:

Syntax: /FI[ ]pathname

The /FI option has the same effect as including the file at top of every source file.
