I'm using Visual Studio and need to set VCPKG_KEEP_ENV_VARS and other environment variables

[perdrix52]

When I build my projects using CMake, I can add to CMakePresets.json e.g.:

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

but I cannot see how to achieve the equivalent function using standard Visual Studio Solution/Project files. In the VS environment the variable QTDIR is set so I can reference it in my project configurations using $(QTDIR), but I can't see how I can set that into the EV of the same name and set VCPKG_KEEP_ENV_VARS.

Setting this into the System EVs is not a good solution - I need to do this at the VS Solution or Project level.

Help please.

I worked out how to do this using Property Manager and setting macros up that are exported as EVs
