Jemand

Hi. I am getting an error while building Qt6.5.3 QtWebEngine for Windows x64.
Here is the build configuration:

..\configure -prefix C:\qt6_x64 -opensource -debug-and-release -confirm-license -opengl desktop -nomake tests -nomake examples -skip qthttpserver -skip qtlocation -skip qtspeech -skip qtgrpc -skip qt3d -skip qtcharts -skip qtcoap -skip qtconnectivity -skip qtdatavis3d -skip qtdoc -skip qtlottie -skip qtmqtt -skip qtnetworkauth -skip qtopcua -skip qtremoteobjects -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtwayland -skip qtwebengine -skip qttranslations -skip qtquickeffectmaker -skip qtquick3dphysics -skip qtgraphs  -openssl-linked -- -Wno-dev -DOPENSSL_ROOT_DIR="C:\Q\openssl-3.0.13-WIN64A\build" -DOPENSSL_INCLUDE_DIR="C:\Q\openssl-3.0.13-WIN64A\build\include" -DOPENSSL_USE_STATIC_LIBS=ON -DFFMPEG_DIR=C:\Users\user\Desktop\vcpkg\installed\x64-windows

C:\qt6_x64\bin\qt-configure-module.bat ../qtwebengine -- -Wno-dev

Here is the error:
