Set Environement Variable In Vscode With The Cmake Plugin

Set up Cmake Kit In Vscode

First, open up your current kits using Ctrl + shift + P and "Edit User-Local Cmake Kits". Copy the data from the one you are currently using.

Create a file in the .vscode folder called cmake-kits.json and format it like below:

[{
    "name": "<name of kit>",
    "environmentVariables": {
        "<name of variable>": "1"
    },
    <DATA FROM EXISTING CMAKE KIT GOES HERE>
}]

Then, change your active kit and rebuild.
