Building fmhs Fails Due to Missing Dependencies

[thedward]

Description

Building fmhs fails due to missing dependencies in the Formality.cabal file.

To Reproduce

Execute the commands:

git clone https://github.com/Kindelia/Kind
cd Kind/bin/hs
cabal build
cabal install

The output:

Build profile: -w ghc-8.10.7 -O1
In order, the following will be built (use -v for more details):
 - Formality-0.1.0.0 (lib) (first run)
 - Formality-0.1.0.0 (exe:fmhs) (first run)
Preprocessing executable 'fmhs' for Formality-0.1.0.0..
Preprocessing library for Formality-0.1.0.0..
Building executable 'fmhs' for Formality-0.1.0.0..
Building library for Formality-0.1.0.0..

cabal: Failed to build Formality-0.1.0.0.
Failed to build exe:fmhs from Formality-0.1.0.0.

Adding filepath and directory to the dependencies in the cabal file allows it to compile without errors.

Expected behavior

I would expect it to compile without errors.

Environment

OS	Debian GNU/Linux 11
Kind Version	1.0.112 (master)
GHC Version	8.10.7
Cabal Version	3.6.2.0

Unfortunately we are only mantaining the javascript release, so haskell won't work. But you can use the javascript version to try Kind.
