<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>
[NOTE] You can retry with '--assume-depexts' to skip this check, or run 'opam option depext=false' to permanently disable handling of system packages.
Running the system package manager non-interactively requires '--confirm-level=unsafe-yes'.
opam believes some required external dependencies are missing. opam can:
> 1. Run C:\opam\.opam\.cygwin\setup-x86_64.exe to install them (may need root/sudo access)
2. Display the recommended C:\opam\.opam\.cygwin\setup-x86_64.exe command and wait while you run it manually (e.g. in another terminal)
3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
4. Abort the installation
