Remove all OpenGL/GLEW code and dependencies. The Vulkan renderer has
been the sole active backend for months; these files were dead code.
Deleted (8 files, 641 lines):
- rendering/mesh.cpp+hpp: OpenGL VAO/VBO/EBO wrapper (never instantiated)
- rendering/shader.cpp+hpp: OpenGL GLSL compiler (replaced by VkShaderModule)
- rendering/scene.cpp+hpp: Scene graph holding Mesh objects (created but
never populated — all rendering uses Vulkan sub-renderers directly)
- rendering/video_player.cpp+hpp: FFmpeg+GL texture uploader (never
included by any other file — login video feature can be re-implemented
with VkTexture when needed)
Cleaned up:
- renderer.hpp: remove Scene forward-decl, getScene() accessor, scene member
- renderer.cpp: remove scene.hpp/shader.hpp includes, Scene create/destroy
- application.cpp: remove stale "GL/glew.h removed" comment
- CMakeLists.txt: remove find_package(OpenGL/GLEW), source/header entries,
and target_link_libraries for OpenGL::GL and GLEW::GLEW
- PKGBUILD: remove glew dependency
- BUILD_INSTRUCTIONS.md: remove glew from all platform install commands
vulkan-headers provides <vulkan/vulkan.h> which is required at compile
time by imgui (imgui_impl_vulkan.cpp) and vk-bootstrap. On Arch,
vulkan-devel is not a package name — the headers must be installed
explicitly via vulkan-headers.
Also replace vulkan-devel with the correct individual packages:
vulkan-headers (build-time headers)
vulkan-icd-loader / vulkan-tools (runtime + utilities)
Fixes build failure: fatal error: vulkan/vulkan.h: No such file or directory
Linux CI was missing libvulkan-dev, vulkan-tools, and glslc, causing
find_package(Vulkan REQUIRED) to fail. Also update BUILD_INSTRUCTIONS
Ubuntu and Arch sections to include Vulkan/shaderc packages.
- extract_assets.sh: detect Homebrew and pass CMAKE_PREFIX_PATH,
OPENSSL_ROOT_DIR, and PKG_CONFIG_PATH when auto-building on macOS
(bare cmake couldn't find Homebrew deps)
- README.md: fix macOS brew command that had comments after line
continuations (breaks shell execution)
- BUILD_INSTRUCTIONS.md: expand macOS asset extraction section with
auto-build note and expansion targets
- Add missing MSYS2 packages to CI: vulkan-loader, vulkan-headers,
shaderc, stormlib (both x86-64 and arm64), unicorn (arm64)
- Make vulkan-1.dll copy conditional via find_file (fixes MSYS2 builds)
- Use find_library for wininet/bz2 in asset_extract (graceful fallback)
- Add extract_assets.ps1 and extract_assets.bat for Windows users
- Expand BUILD_INSTRUCTIONS.md with MSYS2, vcpkg, and macOS sections
- Update README.md to reference Windows scripts and platforms
