Owner

We ship SDL3 3.2.30 (sky_line/3p-sdl3 v3.2.30-r1, linux64 + windows64). Update to the latest upstream SDL3 release. At filing time that is 3.4.18 (release-3.4.18, 829a65d76); check for anything newer when picking this up.

Why

The SDL 3.4 series has the newer gamepad support that Game Control (#1203 / #1204) and GunMetal-DX's controller extensions (#1207) use: Steam Controller handling, gyro, trackpad, and updated built-in mappings.
GunMetal-DX already ships Linux SDL 3.4.18, built from OUR 3p-sdl3 recipe against the newer tag (stock upstream, no patches). We build our own rather than using their binary.

Scope

Build 3.4.x in sky_line/3p-sdl3 with the existing recipe, for linux64 and windows64. Keep the Linux portability pins (glibc baseline, make glibc-check) and the Wayland / libdecor setup (#197).
Make sure the Windows package has the gamepad backends (HIDAPI, XInput / RawInput, GameInput if available). Make sure the Linux package has evdev / udev joystick support.
Update indra/cmake/3p_manifest.json with scripts/3p/manifest.py update, and attach the release assets on our Forgejo.
Read the SDL 3.2 -> 3.4 migration notes for our window layer (indra/llwindow/llsdl.cpp, llwindowsdl.cpp, llgamepadsdl.cpp):
- deprecated or renamed APIs;
- clipboard, IME, cursor, HiDPI and Wayland behaviour changes.
Smoke test on Linux X11, Linux Wayland and Windows (cross build plus Wine, then real Windows):
- window, fullscreen (#919), IME;
- clipboard, cursor;
- gamepad hot-plug.

Blocks: #1207 (GunMetal-DX stage 2 controller extensions). Related: #1203, #1204.
