    Description

      I try to build Qt via LLVM on Windows. The cmake configure succeeds, but the build failes with:

      /qglobal.cpp:5:10: fatal error: 'qplatformdefs.h' file not found
      #include "qplatformdefs.h"
               ^~~~~~~~~~~~~~~~~


      You should be able to reproduce this by the following steps via PowerShell:

      Set path to the tools which should be used (CMake, Ninja, Python, LLVM):

      # Set environement variable PATH
      $env:Path = 'C:\Temp\llvm\bin;C:\Temp\python;C:\Temp\cmake\bin;C:\Temp\ninja;C:\Windows\system32;C:\Windows;C:\Windows\System32\WindowsPowerShell\v1.0\'

      Install these tools to the paths we set:

      cd C:\Temp

      Invoke-WebRequest -Uri "https://github.com/ninja-build/ninja/releases/download/v1.11.1/ninja-win.zip" -OutFile ninja.zip
      Expand-Archive ninja.zip -DestinationPath ninja

      Invoke-WebRequest -Uri "https://github.com/Kitware/CMake/releases/download/v3.26.3/cmake-3.26.3-windows-x86_64.zip" -OutFile cmake.zip
      Expand-Archive cmake.zip -DestinationPath .
      mv cmake-3.26.3-windows-x86_64 cmake

      Invoke-WebRequest -Uri "https://www.python.org/ftp/python/3.11.3/python-3.11.3-embed-amd64.zip" -OutFile python.zip
      Expand-Archive python.zip -DestinationPath python

      Invoke-WebRequest -Uri "https://github.com/llvm/llvm-project/releases/download/llvmorg-16.0.3/LLVM-16.0.3-win64.exe" -OutFile llvm.exe

      Download and extract Qt:

      Invoke-WebRequest -Uri "https://ftp.fau.de/qtproject/archive/qt/6.5/6.5.0/single/qt-everywhere-src-6.5.0.zip" -OutFile qt.zip
      Expand-Archive qt.zip -DestinationPath .

      Configure Qt:

      {{mkdir -p C:\Temp\build
      cd C:\Temp\build
      cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DQT_BUILD_SUBMODULES=qtbase -DQT_BUILD_EXAMPLES=OFF -DQT_BUILD_TESTS=OFF -DBUILD_WITH_PCH=OFF -DQT_BUILD_TOOLS_BY_DEFAULT=OFF -DFEATURE_precompile_header=OFF -DCMAKE_INSTALL_PREFIX=c:\Temp\install c:\Temp\qt-everywhere-src-6.5.0
      }}

      My output is:

      WARNING: Basic cpp/winrt support missing. Some features might not be available.

      --

      Qt is now configured for building. Just run 'cmake --build . --parallel'

      Once everything is built, you must run 'cmake --install .'
      Qt will be installed into 'C:/Temp/install'

      To configure and build other Qt modules, you can use the following convenience script:
              C:/Temp/install/bin/qt-configure-module.bat

      If reconfiguration fails for some reason, try removing 'CMakeCache.txt' from the build directory
      Alternatively, you can add the --fresh flag to your CMake flags.

      -- Configuring done (58.9s)
      -- Generating done (2.0s)

      Build Qt:

      cmake --build . --parallel 1
