Qt 6.6静态编译构建Scenegraph示例时链接oleaut32库失败问题

我在Windows上编译了Qt 6.6静态版本，尝试构建静态项目时，编译“Scenegraph”示例程序失败，出现以下链接错误：

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: C:/Qt/6.6.0-static/plugins/networkinformation/libqnetworklistmanager.a(qnetworklistmanagerevents.cpp.obj):qnetworklistmanagerevents.cpp:(.text$_ZN25QNetworkListManagerEvents24checkBehindCaptivePortalEv+0x82): undefined reference to `__imp_VariantInit'

collect2.exe: error: ld returned 1 exit status

使用的编译器为gcc 13.2.0。

从报错信息来看，需要链接oleaut32.lib，但Qt编译时已经包含该库，且我在调试模式下测试过oleaut库是可用的。我已经尝试在项目.pro文件中添加LIBS += -loleaut32，但仍然出现相同错误。

部分编译输出显示链接命令中确实包含了该库：

libqwindows.a -ldwmapi -limm32 -loleaut32 -lsetupapi -lshlwapi -lwinspool
lib/libQt6Network.a -lbrotlidec -lbrotlicommon

我的项目.pro文件内容如下：

QT += quick
QT += opengl
CONFIG += c++2a
CONFIG += static
QMAKE_CXXFLAGS += -std=c++2a
LIBS += -lgmp

SOURCES += \
    Squircle.cpp \
    glrenderer.cpp \
    main.cpp \

RESOURCES += \
    qml.qrc

qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

HEADERS += \
    Squircle.h \
    glrenderer.h \

DISTFILES += main.qml

除了改用动态编译，还有什么解决方案？
