The [add-dependent-file](https://github.com/yaitskov/add-dependent-file) library provides a safer wrapper around [addDependentFile](https://hackage.haskell.org/package/template-haskell/docs/Language-Haskell-TH-Syntax.html#v:addDependentFile) that checks that `extra-source-files` section in the cabal file contains **addDependentFile** argument and issues a correspondent compilation warning if it does not, because `addDependentFile` has no effect otherwise.
