It builds fine on Linux and OSX.
The problem is that the lambdacube-ir git repository contains symbolic links, that can not handled by Windows. The sym links are not presented in the hackage lambdacube-ir releases though.

Yes, the symlinks are the problem under Windows. There's a slightly inconvenient but working solution though. Start a Git shell as administrator run the following commands:

git config core.symlinks true
git reset --hard HEAD

Afterwards, whenever you want to execute git pull for this repository, you have to do it in an admin shell.
