- From `roles` only `private.h`, `h1`, `http`, `listen`, `pipe`, `raw`, `ws`
- From `roles/http` exclude `minilex.c`
- From `roles/http/server` exclude `access-log.c`, `lws-spa.c`, `ranges.c`, and `rewrite.c`
- From `roles/ws` exclude `ext` folder.
- From `tls` exclude `openssl` folder.
- Also copy `win32helpers/` from `win32port/` inside `thirdparty/libwebsockets`
- A fix has been added to allow building for 32-bits UWP, replacing `GetFileSize[Ex]` and `CreateFileW` with supported functions.
There is a diff for this change in `thirdparty/libwebsockets/uwp_fixes.diff`
- A fix to disable V6ONLY flag from IPv6 sockets (on by default on some systems) has been also applied.
The diff for this change can be found in `thirdparty/libwebsockets/ipv6_fixes.diff`
Important: `lws_config.h` and `lws_config_private.h` contains custom
Godot build configurations, check them out when updating.
