Dear Andy, here you can find a batch file, which sets up a Cygwin from scratch with a defined set of packages:
https://github.com/coq/coq/blob/master/dev/build/windows/MakeCoq_MinGW.bat The setup of Cygwin takes about 2 minutes and is without any user interaction. I would say, this is a more reasonable approach. If you want a fixed environment, you should use your own Cygwin repo. It later calls a shell script which builds ocaml, menhir, libraries like lablgtk and eventually Coq, but I guess this wouldn't be useful for you because this is a MinGW Ocaml and I guess (just a guess) you are using a Cygwin OCaml. But there is no reason why one couldn't setup opam on Cygwin in a similar way. I think there are also some Cygwin / opam scripts in the CI of Coq. If this would be useful for you, I can point you to the respective scripts.
