Getting an LSP working in dune

[H-ANSEN]

I'm using Neovim with ocamllsp and lsp-zero. I'm having some difficulties getting my LSP to run while in the Dune code base. I was wondering if anyone else has a similar setup and has resolved this issue in the past? I am notably getting the following diagnostic message at the top of each source file:

The current Merlin configuration has been generated by another, incompatible, version of Dune. Please rebuild the project. (Using the same version of Dune as the one running the ocaml-merlin server.)

I assume that this has to do with the whole Dune building Dune aspect, but sense I am running the LSP through lsp-zero I'm unsure how I would go about handling Merlin.

The correct steps should be:

$ make dev
$ ./dune.exe build @install
$ ./dune.exe exec -- nvim

The launched neovim should have the correct dune in its environment.

Thank you! Works perfectly 😸
