From 74ba3823f8e603458981dc4fcab9665cfebe24b9 Mon Sep 17 00:00:00 2001 From: elderorb Date: Fri, 14 Aug 2026 16:27:18 +0200 Subject: [PATCH 1/2] windows: fix native MSVC/Vulkan build portability Make the native Windows MSVC/Vulkan path buildable by centralizing the missing portability shims and fixing the packaging/link seams that block the shared library and test binaries. This commit introduces the shared platform helpers, ports the Windows-facing callsites that needed them, and wires the Windows shared-library / Vulkan loader path so the existing CI lanes can exercise it. Later follow-up commits tighten the scope after review.
