The problem won't be solved by this,
but you should also set os.subsystem=cygwin in your profile.
See https://github.com/conan-io/conan/blob/201480146740d2ab298b9f360037ab9e56c2a6a5/conans/client/migrations_settings.py#L16

In the past, I noticed zilb has also problems when building in msys2.
I'll look into that, and ping you when I need more information.
