staticDirPathInProjectBuildDirPath

In the Creact React App setup the, when you run yarn build, a build/ directory is generated. I this directory there's a static directory/. If, in your setup it's an other directory you can use this option:

package.json

{
    "keycloakify": {
        "staticDirPathInProjectBuildDirPath": "a/b/c"
    }
}

By default it's "static".
