Solution-wide #define

Question

Is there a way to globally declare a #define?

Like I want to have a file that has for instance,

#define MONO

and I want all source-

Answer 1

I don't know of a solution wide definition, but I was able to quickly add a preprocessor definition to all projects by doing the following:

1. hold ctrl and select each project
2. right click on any selected project and choose Properties
3. go to C/C++ --> Preprocessor
4. click the little down arrow beside Preprocessor Definitions
5. choose
6. add my definition after
7. OK out of the menus

I'm using Visual Studio Community 2019 with a C code base.
