I have this setup:

```
// tsconfig.json

{
  "compilerOptions": {
    "rootDir": "src",
  ...
}

...

//jest.config.ts

...
globals: {
  'ts-jest': {
    tsconfig: {
      rootDir: '.'
    }
  }
}

```

But when I run jest I get an emit error saying that typescript files need to be under root, it seems like this "rootDir" compiler option is being ignored.

I don't want my /test or my configs to be under /src and I don't want it to be compiled to /lib or to be emitted.

I also can't exclude it using `exclude` because then it's also excluding the types for my .ts files which are outside the project, which makes using ts-node really difficult.
