Expected Behavior

I have a controller which returns a type that is defined in another file, however TSOA fails to find it during generation. Not sure if this is a relative path issue?

Current Behavior

import { IType } from 'folder/file';

@Post('{path}')
createOrUpdateType(@Path() path
    ): Promise<IElementsResponse> {
...stufff
}

Possible Solution

Steps to Reproduce

run tsoa spec-and-routes with some thing similar to above:

Generate routes error.
 GenerateMetadataError: No declarations found for referenced type IElementsResponse.

Hello there Enquier 👋

Thank you for opening your very first issue in this project.

We will try to get back to you as soon as we can.👀

Similar to the closed (stale) issue #1653 ?

[Enquier]

I did a little more testing and it seems as though if I put in a full relative path it works: "eg ../../path/to/file as opposed to path/to/file.
Is there a config I am missing or is this just a limitation of the tool

[Enquier]

Added some config to compiler options... didn't realize TSOA wasn't taking from the local tsconfig (my bad)
