How to change predefined macros in Visual Studio 2015?

Question

I am trying to modify predefined environment macros in Visual Studio 2015. In particular, this: VC_IncludePath

I see it and its meaning, but I cannot change it. I see no way to do this.

Answer 1

You can edit this file:

C: \ Program Files (X86) \ MSBuild \ Microsoft.Cpp \ v4.0 \ V140 \ Microsoft.Cpp.Common.props

Answer 2

The place to change this environment variable is on the project properties page. Configuration Properties -> VC ++ Directories, as described in the MSDN documentation .
