Qt6 Static build for macOS problem: Undefined symbols for architecture x86_64 and issues with libraries linking.

The issue appears while compiling QML project (qmake) under Qt6 Static build.

The compilations process exits with code 2 and reporting "Undefined symbols for architecture x86_64".

Further analisys of compile output shows number of issues, which seems to be libraries/plugins linking to Static build:

Undefined symbols for architecture x86_64: "qml_register_types_QtQuick_Layouts()", referenced from: qt_plugin_instance_QtQuickLayoutsPlugin() in libqquicklayoutsplugin.a(plugin.cpp.o) "qml_register_types_Qt_labs_settings()", referenced from: qt_plugin_instance_QmlSettingsPlugin() in libqmlsettingsplugin.a(plugin.cpp.o) ... ... ... libqtvirtualkeyboard_pinyin.a(pinyindecoderservice.cpp.o) "_im_set_max_lens", referenced from: QtVirtualKeyboard::PinyinDecoderService::setLimits(int, int) in libqtvirtualkeyboard_pinyin.a(pinyindecoderservice.cpp.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) make: *** [ATU_connect.app/Contents/MacOS/ATU_connect] Error 1 21:53:54: The process "/usr/bin/make" exited with code 2. Error while building/deploying project ATU_connect (kit: 6.1.0_static) When executing step "Make"

Same resuilt/same error output on Static builds of Qt versions 6.0.3 and 6.1.0-beta3 and under Xcode 12.0 and 12.4.
