  <!--
    Fix: The WDK MessageCompile task does not honour KernelModeTypes=true.
    It omits the -km flag regardless of SDK version, producing a 40-line
    bare EVENT_DESCRIPTOR header instead of the 961-line kernel-mode wrapper
    macro header that src/IntelAvbFilter.h must contain.

    This target re-runs mc.exe with -km AFTER MessageCompile (which may have
    generated the wrong header) and BEFORE ClCompile (which needs the macros).
    TargetPlatformVersion is set to 10.0.22621.0 by Build-Driver.ps1.

    Fixes CI: GitHub-hosted runners have SDK 10.0.26100.0 as default but the
    install-wdk action installs 10.0.22621.0.  Build-Driver.ps1 passes
    /p:TargetPlatformVersion and /p:WindowsSdkVerBinPath to pin mc.exe.

    Fix: FilesToPackage items in the vcxproj are hardcoded to
    "build\x64\Debug\IntelAvbFilter\..." regardless of $(Configuration).
    Introduced in commit 202ac68: "$(OutDir)"-based items were changed to
    an absolute local-machine path (D:\Repos\...) and then to a relative
    path still locked to the Debug folder.  When building Release the
    Debug path does not exist, causing MSB3030 in WindowsDriver.common.targets.

    This ItemGroup runs at import time (after the vcxproj ItemGroups) and:
      1. Removes the hardcoded Debug-only items.
      2. Adds configuration-correct $(OutDir)-based replacements so that
         both Debug and Release builds package the right files.
