How do I modify Visual Studio 2015 predefined macros?

Question

I'm trying to modify a predefined environment macros in Visual Studio 2015. Specifically this: VC_IncludePath

I can see it and its value, but I can not modify it. I don't see the option to do it.

*Don't*. This is a holdover from old versions and has been hidden and obscured greatly by Microsoft. Instead, just modify your projects to include the necessary additional folders. When you do it the way you are attempting, then each and every developer must change this too. If you make it a project setting, it is self contained. — crashmstr, Jul 24 '15 at 17:34
@crashmstr The down-side of *not* doing it, is that it's including the wrong paths. So you need a function that exists in a version of `stdlib.h` in *this* SDK, but doesn't exist in *that* sdk path. We need some way to stop using old SDK paths. — Ian Boyd, Jun 01 '20 at 19:08

You can edit this file:

C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Common.props

The value of this macro is automatically generated from the versions you have set in the property pages. Select Project, Properties, Configuration Properties, General and check that the Target Platform Version and Platform Toolset are correct for your installation.

For other versions, search 'Microsoft.Cpp.Common.props' in windows explorer at C:. You may find several depending on versions installed. Then, right click the version you want and Open > choose VS (easier to see the lists) or any. However, no VS environment variables are there to edit.

The place to change that environment variable is in the project property page Configuration Properties -> VC++ Directories as described in the MSDN documentation.

If you look at my post, you will note a link to a screenshot, where I show that page without option to edit the macros. – ErnestM Jul 27 '15 at 13:29
Click the folder-with-a-star button to add a new path. Uncheck 'Inherit from parent or project defaults' to start with no include paths. – Khouri Giordano Jul 27 '15 at 21:47
He didn't ask how to add a new directory, he asked how to add/edit a macro – Aaron Apr 23 '16 at 22:08
If you uncheck 'Inherit from parent or project defaults', you will have to add the paths you want. – Khouri Giordano Apr 26 '16 at 21:54
