circular dependency between unmark.cli and notty

[edwintorok]

I tried to run the benchmark, which depends on the 'unmark' package that is not on opam.
I tried pinning it, which went fine:
opam pin add unmark https://github.com/pqwy/unmark.git

Then tried running the benchmark:

dune exec ./speed.exe
Entering directory '/var/home/edwin/git/notty'
Error: Conflict between the following libraries:
- "notty" in _build/default/src
- "notty" in /var/home/edwin/.opam/5.0.0/lib/notty
  -> required by library "unmark.cli" in
     /var/home/edwin/.opam/5.0.0/lib/unmark
-> required by executable speed in benchmarks/dune:2
-> required by _build/default/benchmarks/speed.exe

Lets try removing notty and use the one I'm just building locally with dune, but that removes unmark too:

opam remove notty
[WARNING] Opam package conf-gles2.1 depends on the following system package that can no longer be found: mesa-libGLES-devel
cd ..
The following actions will be performed:
  ⊘ remove unmark ~dev* [uses notty]
  ⊘ remove notty  0.2.3
===== ⊘ 2 =====
Do you want to continue? [Y/n] y

And since unmark doesn't use dune I can't just drop it in a subdir to build it together.

Is there a way to break the cycle?
