Expose Typescript type declarations for untyped package

I'm using an untyped (commonJS) external package to build my library. Therefore, I created a .d.ts file to add those typings. However, these type declarations are not carried over to in my output bundle. How can I assure that they get bundled in my library so that the consumer gets properly typed components?

// untyped package => ./src/types/untypedPackage.d.ts;

declare module "untyped-package" {
   // type declarations here
}

I've read that I probably need to use a triple-slash directive on the consumer end, but I also read that it's not a good practice. What's the best way to make this automatic without fiddling with triple-slash directives or copying .d.ts files + to build folder + re-importing them in the consumer project?

Don't put the types in /src! Many libraries just put it in the root folder. So you won't need to copy it over, but make sure to set typeRoots in the tsconfig file.
