    Description

      Compilation fails on Windows 10, using Visual Studio 2022 17.13.6

      Here is the build script:

       

       
set PYTHON_EXE="D:/vcpkg2/installed/x64-windows/tools/python3/python.exe"
set CMAKE_EXE="D:/vcpkg2/downloads/tools/cmake-3.30.2-windows/cmake-3.30.2-windows-i386/bin/cmake.exe"
set QTPATHS_EXE="D:/vcpkg2/installed/x64-windows/tools/Qt6/bin/qtpaths.exe"
set OPENSSL_PATH="D:/vcpkg2/installed/x64-windows/bin"
set LLVM_INSTALL_DIR=D:/vcpkg2/downloads/tools/llvm-18.1.8
 
%PYTHON_EXE% setup.py install --verbose-build --cmake %CMAKE_EXE% --qtpaths %QTPATHS_EXE% --openssl %OPENSSL_PATH% --module-subset=Core,Gui,Widgets,Help,Network,Concurrent,DBus,Designer,OpenGL,OpenGLWidgets,PrintSupport,Qml,Quick,QuickControls2,QuickTest,QuickWidgets,Xml,Test,Sql,Svg,SvgWidgets,UiTools --skip-docs --reuse-build --parallel=8

      Then apiextractor fails with tons of errors like this for each modules:

      D:\vcpkg2\downloads\tools\llvm-18.1.8\lib\clang\18\include\emmintrin.h:43:9: error: _Float16 is not supported on this target

      It fails for every module. I attached error log just for QtOpenGL, but the log is pretty similar for all other modules, none of them work.
