When attempting to build the Qt 3D: Planets QML Example example provided by Qt for WebAssembly, I encountered an error indicating unknown modules in QT during the build process. This issue prevents successful compilation and execution of the example.

Steps to reproduce: 
1. Activate PATH and other environment variables in the terminal

source ./emsdk_env.sh 

2. Build Qt 3D: Planets QML Example

/path/to/Qt/6.2.9/wasm_32/bin/qmake /path/to/Qt/Examples/Qt-6.2.9/qt3d/planets-qml/ 

error log: 

Project ERROR: Unknown module(s) in QT: 3dextras concurrent 3dcore 3drender 3dinput 3dquick 3dquickrender 3dquickinput 3dquickextras 

Expected Outcome: The "planets-qml" example should build successfully, allowing for execution in the WebAssembly environment.

Actual Outcome: During the build process, I encountered the following error message: "Project ERROR: Unknown module(s) in QT: 3dextras concurrent 3dcore 3drender 3dinput 3dquick 3dquickrender 3dquickinput 3dquickextras"
