Add SPIRV-Tools source directory to include paths for pass_manager.h

[Copilot]

Build fails on Vulkan SDK 1.4.304.1 because spirvgenerator.cc includes spirv-tools/libspirv.h, which transitively includes pass_manager.h — an internal header in source/opt/ not exposed in the public API.

Changes

• Added $VULKAN_SDK/source to SPIRV-Tools-opt target's INTERFACE_INCLUDE_DIRECTORIES in code/compiler/CMakeLists.txt
• Guarded with existence check to maintain compatibility across SDK versions

if(DEFINED ENV{VULKAN_SDK})
    set(SPIRV_TOOLS_SOURCE_DIR "$ENV{VULKAN_SDK}/source")
    if(EXISTS "${SPIRV_TOOLS_SOURCE_DIR}")
        set_property(TARGET SPIRV-Tools-opt APPEND
        PROPERTY
            INTERFACE_INCLUDE_DIRECTORIES "${SPIRV_TOOLS_SOURCE_DIR}")
    endif()
endif()

This works around a packaging issue in the SDK where internal implementation headers leak through the public API.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Can you find which file includes pass_manager.h?
