`tsconfig.json` exclude not respected

Here is my config:

```json
{
"compilerOptions": {
"target": "es2015",
"skipLibCheck": true,
"exclude": [
"fixture/*.ts"
]
}
}
```

when I run `check-dts test/**` I see lots of errors inside `fixture` files:

How to exclude it? I want check only `test` directory, could you please help me?
