Qt Webassembly via conan package manager - "Could NOT find Qt6Quick"

[just_a_developer]

Hello,

I am following this guide :
https://www.qt.io/blog/installing-qt-via-conan-package-manager
specifically this gif : https://www.qt.io/hs-fs/hubfs/conan_demo_app_build.gif?width=1600&name=conan_demo_app_build.gif .

I am trying to figure out how this process could be used to cross-compile for Qt Webassembly from macOS x86_64.
Here is the project that I have so far : https://wetransfer.com/downloads/859e405c7241c6fd9353944a9e591ddf20220201114259/cffcaf1de2ba8e3cd57fcfc1c9ff83af20220201114312/e85342 .
The ./buildWasm.sh is supposed to build the project, but it fails with this error :
"
-- Could NOT find Qt6Quick (missing: Qt6Quick_DIR)
CMake Error at CMakeLists.txt:15 (find_package):
Found package configuration file:

/Users/myUser/.conan/data/qtbase/6.2.2/qt/everywhere/package/5f6084cf36d2dec9c03d119ccdb11027ce3fa5ba/lib/cmake/Qt6/Qt6Config.cmake

but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
FOUND. Reason given by package:

Failed to find Qt component "Quick".

Expected Config file at
"/Users/myUser/.conan/data/qtbase/6.2.2/qt/everywhere/package/5f6084cf36d2dec9c03d119ccdb11027ce3fa5ba/lib/cmake/Qt6Quick/Qt6QuickConfig.cmake"
does NOT exist
"

...and indeed : QtQuick is in qtdeclarative, and not in qtbase.

How could I fix this issue?

A bit of an update :
I just tried this widget application : Qt/Examples/Qt-6.2.1/widgets/richtext/syntaxhighlighter/ .

It works well, using the conanfile.txt and the buildWasm.sh that I have in the zip.
I am copying the contents of those files here :
conanfile.txt :

[requires]
qtbase/6.2.2@qt/everywhere
qtdeclarative/6.2.2@qt/everywhere

buildWasm.sh :

set -e

conan install qtbuildprofiles/6.2.2@qt/everywhere -r qt

mkdir -p wasmBuildMachine
cd wasmBuildMachine
conan install -u ../conanfile.txt --profile=../macos-universal-clang --build=never --update --generator=virtualenv -r qt
source activate.sh
QT_HOST_PATH=$(echo "$Qt6_DIR" | sed "s#/lib/cmake/Qt6##g")
echo "QT_HOST_PATH : $QT_HOST_PATH"
source deactivate.sh
cd ..

conan install -u conanfile.txt --profile=macos-webassembly-x86_64-clang --build=never --update --generator=virtualenv -r qt
source activate.sh

QT_CMAKE=$(echo "$Qt6_DIR" | sed "s#/lib/cmake/Qt6##g")
QT_CMAKE+="/bin/qt-cmake"
echo "QT_CMAKE : $QT_CMAKE"

mkdir -p buildWasm
cd buildWasm
echo "$QT_CMAKE ../ -G Ninja -DCMAKE_BUILD_TYPE=Release -DQT_HOST_PATH=$QT_HOST_PATH"
$QT_CMAKE ../ -G Ninja -DCMAKE_BUILD_TYPE=Release -DQT_HOST_PATH=$QT_HOST_PATH
VERBOSE=1 cmake --build . --config Release --clean-first

Here is a screenshot as well, about this Example application, that I compiled for WebAssembly, running in Chrome :

So it seems like that the issue is with the QtQuick module...
Possible solution ideas are very well welcomed!
I tried many things, but nothing worked so far.

A quick update : this https://bugreports.qt.io/browse/QTBUG-94524 (Introduce a QT_ADDITIONAL_HOST_PACKAGES_PREFIX_PATH variable) will solve the issue above.
