building with cmake 3.31 gives ODR violation warnings on webassembly

I setup a ci pipeline that tests building qt for webassembly with several cmake versions. it works fine with cmake 3.29 and 3.30, but gives the following warning when using cmake 3.31:

[10/81] Generating .rcc/qmlcache/galleryexample_qmlcache_loader.cpp

[11/81] Automatic QML type registration for target galleryexample

Warning: qquickforeignutils_p.h:107: Multiple C++ types called QEventPointDerived found!

(other occurrence in : qquickforeignutils_p.h : 107 )

This violates the One Definition Rule!

Warning: qquickforeignutils_p.h:107: Multiple C++ types called QEventPointDerived found!

(other occurrence in : qquickforeignutils_p.h : 107 )

This violates the One Definition Rule!

Warning: qqmldelegatecomponent_p.h:70: Multiple C++ types called QQmlDelegateChooser found!

(other occurrence in : qqmldelegatecomponent_p.h : 70 )

This violates the One Definition Rule!

... many more similar warnings follow

there are additional warnings when building the wasm version of qt:

CMake Warning (dev) at qtbase/cmake/QtPublicSbomGenerationHelpers.cmake:57 (cmake_parse_arguments):
The LICENSE keyword was followed by an empty string or no value at all.
Policy CMP0174 is not set, so cmake_parse_arguments() will unset the
arg_LICENSE variable rather than setting it to an empty string.

I'm using the following commands for building:
git clone --branch ${{matrix.qtversion git://code.qt.io/qt/qt5.git qt_src}}
QT_SRC_CONFIGURE=$(pwd)/qt_src/configure
QT_WASM_ROOT_DIR=$(pwd)/wasmqt_install
BUILD_DIR=$(pwd)/build
mkdir qt_wasm_build
cd qt_wasm_build
$QT_SRC_CONFIGURE -qt-host-path $QT_ROOT_DIR -platform wasm-emscripten -init-submodules -submodules qtdeclarative,qtbase -skip qtlanguageserver,qtquicktimeline,qtimageformats
$QT_SRC_CONFIGURE -qt-host-path $QT_ROOT_DIR -platform wasm-emscripten -release -optimize-size -submodules qtdeclarative,qtbase -skip qtlanguageserver,qtquicktimeline,qtimageformats -make libs -gui -no-feature-thread -prefix "${QT_WASM_ROOT_DIR}/"
cmake --build . --parallel && cmake --install .
cd ..
${QT_WASM_ROOT_DIR}/bin/qt-cmake -G Ninja -B $BUILD_DIR -DCMAKE_BUILD_TYPE=MinSizeRel -DCMAKE_INSTALL_PREFIX=install -S .
cmake --build $BUILD_DIR --target install 2>&1 | tee build_output.log
if grep -q "One Definition Rule" build_output.log; then
   echo "Error: Found 'One Definition Rule' in build output."
   exit 1
fi
