Generated source link JSON

In the [/SOURCELINK](https://docs.microsoft.com/en-us/cpp/build/reference/sourcelink?view=msvc-160) documentation the following is mentioned "For information on how to use Source Link in your projects, and how to **generate the SourceLink file** as part of your project, see [Using Source Link](https://github.com/dotnet/sourcelink#using-source-link-in-c-projects).". Unfortunately I can't find any information about generating such a file only the [JSON schema](https://github.com/dotnet/designs/blob/main/accepted/2020/diagnostics/source-link.md#source-link-json-schema) and how to create it manually. Could you tell me whether this is even possible and where to find further information in case it is?
