Describe the bug

haskellPackages.citeproc does not provide an executable (for example, entering a nix shell and calling citeproc -h fails with citeproc: command not found

Steps To Reproduce

1. Run nix-shell -p 'haskell.lib.justStaticExecutables haskellPackages.citeproc' --run 'citeproc -h'

Expected behavior

The citeproc executable should be available without an override.

Additional context

I posted about this issue in the discourse. @sternenseemann was very helpful and pointed out that upstream has disabled the executable by default – placing it behind a cabal flag.

He shared the following workaround (which works for me):

nix-shell -p "with haskell.lib.compose; justStaticExecutables (addBuildDepends [ haskellPackages.aeson-pretty haskellPackages.text-icu ] (enableCabalFlag \"executable\" haskellPackages.citeproc))"

It would be nice if the executable were accessible without needing to alter the build dependencies and the flags, though. So I've opened this issue.
