CMake: linker error with Linux Static Libraries while using QtQuick.Controls

Hi!

I’ve built static libraries of Qt6(6.0.3) from Source on Ubuntu 20.04 with the following command:

../qt5/configure -release -static  -prefix ../staticlibs -nomake examples -nomake tests -nomake tools -platform linux-clang

Normal builds work fine and * I'm able to deploy an application. But when I use any version of *QtQuick.Controls in the qml file, I get a linker error like:

/usr/bin/ld: /home/twadmin/qt6/staticlibs/./qml/QtQuick/Controls/Basic/objects-Release/qtquickcontrols2basicstyleplugin_resources_3/.rcc/qmlcache/qtquickcontrols2basicstyleplugin_qml_files_2/qmlcache_loader.cpp.o: in function `_GLOBAL__sub_I_qmlcache_loader.cpp':
qmlcache_loader.cpp:(.text.startup+0x7): undefined reference to `qInitResources_qtquickcontrols2basicstyleplugin_qml_files_2_qmlcache()'

To re-iterate, non-controls builds work fine! I've attached a verbose of the cmake build here.
