Dependency on ocaml-migrate-parsetree

[pitag-ha]

Hello 👋

Is OMP still a test dependency of ppx_cstruct? It is according to its opam file (both opam-repo and local) and according to the test dune file. Looking at the test, it seems to use Ppxlib instead, though, doesn't it?

Yeah, appears to work without it. https://github.com/gentoo/guru/pull/144/files#diff-d332b7c85532a6952cb892936b32297595aaf3df7cb02115388420d51c8bc5e1
