Link failed when using QQuickMaterialStyle in Qt6.4

Sauntor

Environment:

openSUSE leap 15.5
Qt 6.4 from openSUSE's repository

I add these modules in CMakeLists.txt:

Qt6::Quick
Qt6::QuickPrivate

Qt6::QuickControls2
Qt6::QuickControls2Private
Qt6::QuickControls2Impl
Qt6::QuickControls2ImplPrivate

Qt6::QuickTemplates2
Qt6::QuickTemplates2Private

And with these lines in my sources:

# In the .h
#include <QtQuickControls2/private/qquickmaterialstyle_p.h>

# In the .cpp
QQuickMaterialStyle * underlying = ....;
underlying->setTheme(QQuickMaterialStyle::System);

Then, compile is ok, but link is failed with the following info:

x86_64-suse-linux/bin/ld: ../xxx/xxx/libDemo.so: undefined reference to `QQuickMaterialStyle::staticMetaObject'

I also tried adding this to target_link_libraries():
/usr/lib64/qt6/qml/QtQuick/Controls/Material/libqtquickcontrols2materialstyleplugin.so
But it's not work.

If using Qt6.6, the extra CMake modules make it linkable, but no such modules for Qt6.4

So, how to fix this problem?
