Setting environment variables for vcpkg

[Perdrix]

For CMake I can use CMakePresets.json to set e.g.

      "environment": {
        "VCPKG_KEEP_ENV_VARS": "QTDIR",
        "QTDIR": "/opt/Qt/6.9.0/gcc_64"
      },

which can be checked into a VCS.

For MSBuild AFAICT, but only option is to use the Visual Studio Properties Manager (View/Property Manager), and open the Qt section then got to "User macros" and add the names you want to set:

and when you create them tick the box to say that you want them set as an environment variable.

So far so good - BUT AFAICT that isn't preserved anywhere in a file that can be checked into a VCS.

Is there a "better" way to do this please that will preserve the information in a file that I can check in to a VCS?

To answer my own question! I used "Add New Project Property Sheet" to add a property sheet called vcpkg. I told it to save it a file called vcpkg.props in the root directory of the solution. I then configured the two User Macros as above.

I then used "Add Existing Property Sheet" to add this file to all configurations of all the projects in the solution.

Sounds rather awkward, but it does seem to work.
