Should we throw warning instead of error while patched packages not exist

As a example:

```
Patch file found for package vite which is not present at node_modules/vite
```

If we want to build sub-packages independently in monorepo, but we already set `root/package.json`

```
"scripts": {
"postinstall": "patch-package"
}
```

that will interrupt the build process if submodule `root/packages/module-a` does not dependent vite
