Build tier3.lib from real tier3.h globals, not a dummy stub

CO Copilot committed 2 Jul 2026 · b574b5b97d · 1 file, +47 −1

tier3.lib isn't a DLL import lib - public/tier3/tier3.h forward-
declares its own interface types and extern's ~17 global interface
pointers (g_pVGui, g_pMatSystemSurface, g_pDataCache, ...) that real
SDK builds define in a static tier3.lib. The placeholder single-
dummy-symbol archive left every one of those unresolved (g_pVGui etc,
LNK2001) once the link reached vgui_controls.

Compile a real translation unit that includes the actual header and
null-initializes each declared global, so the mangled C++ names match
exactly, then archive that as tier3.lib.
