Install the engine binaries, hl2 and platform base content, and the launch chain from a local Source SDK Base 2013 Multiplayer install, plus a gameinfo.txt with plain relative search paths. Overlaid onto the game content the release pipeline already produces, the depot then runs without SDK Base installed. Relative search paths avoid |appid_243750| resolution, which breaks on case-sensitive filesystems: the engine lowercases the SDK install folder name when resolving those mounts, so all base content silently fails to mount on Linux. Engine binary filenames must also keep their exact casing (GameUI.so and ServerBrowser.so are loaded by name), so the depot pipeline must preserve case. The Linux layout is verified end to end through the Steam Play button. The Windows flow is untested and needs scrutiny before use.

There was a problem hiding this comment.
There's no switch statement in CMAKE right? Google-fu failed.

LOL NOPE NOT THIS! Look at #2019 instead! |

Description
Following the
NEO_INSTALL_LIBRARIES/NEO_INSTALL_RESOURCESpatterns.Stages everything to run without the SDK installed as a dependency, created from the 2013 Source MP SDK.
bin/,hl2/,platform/: engine and base content, exact filename casing preservedntre.*gameinfo.txtwith plain relative search paths instead of|appid_243750|tokensFor local staging and testing. The payload comes entirely from the SDK install, so nothing needs to be compiled first. This PR should update the CI steps as well before leaving draft.
Overlay the output onto the existing game content. That's the depot.
Depot notes: Launch options must pass
-game neo.-steam onlywon't work and that's intentional at this point. The upload pipeline must preserve filename casing.Cause
The Linux launch is broken by two case-sensitivity bugs: the engine lowercases the SDK folder name when resolving
|appid_243750|mounts (so base content silently fails to mount), and the depot shipped lowercased binary names likegameui.sothat the engine dlopens by exact name. Relative paths skip the buggy (or exactly as designed? we'll never know) lookup entirely. Same packaging model as the original NEOTOKYO.Toolchain
TODO
Windows is completely untested at time of writing. Halp!
pathtable resolves every mount inside the install dir.hl2.exetontre.exe,hl2_win64.exetontre64.exe) match what the depot ships, then a Play-button run.
