Building Ppx.exe

[idkjs]

I'm trying to understand how to build a ppx with melange. I can't seem to build the ppx dir using any of the commands in esy.json or package.json. Is it possible to share the build steps?

The only output in _build/ that I get is:

# dune upgrade
# OCAMLPARAM: unset
# Workspace root: /Users/mando/Github/lenses-ppx/packages/ppx
$ /usr/bin/getconf _NPROCESSORS_ONLN > /var/folders/jk/x59dhv6s7151k4mfmshf6v480000gn/T/dunecc4f07.output 2> /dev/null
# Auto-detected concurrency: 8

Thanks for teaching.

I'm also trying to build ppx.exe but no gain. Looking forward to any tip.
