Description

General summary

If cabal file contains foreign-library section, its source files are not tracked with stack build --file-watch. Stack doesn't trigger rebuild when files change.

Steps to reproduce

foreign-library example
  build-depends:
      base
  hs-source-dirs: foreign
  other-modules: Example
  type: native-shared

stack build --file-watch

Expected

Rebuild when foreign/Example.hs is changed.

Actual

Nothing.

Stack version

$ stack --version
Version 1.6.5 x86_64 hpack-0.20.0

Method of installation

brew

Research direction
Investigate how Stack currently tracks source files for regular libraries and executables in the file watch component. Look for the code that watches other modules and add similar handling for foreign library sections. Relevant files might be in the 'src' directory related to building or file watching. Check comments in the issue for any hints, as the issue has been open since 2018.
