Description
Cross compiling qtbase, qtdeclarative, etc. one by one against a Raspbian sysroot and gcc 7.4 (I know gcc 7 is too old for Qt 6 in theory but it should do for now) toolchain, on Ubuntu 20.04 and CMake 3.16.3.
cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DINPUT_opengl=es2 -DFEATURE_developer_build=ON -DBUILD_EXAMPLES=OFF -DBUILD_TESTING=OFF -DCMAKE_TOOLCHAIN_FILE=/home/agocs/Data/rpi/toolchain.cmake -DQT_HOST_PATH=/home/agocs/Data/qtbase -DCMAKE_INSTALL_PREFIX=/usr/local/qt6 -DCMAKE_STAGING_PREFIX=/home/agocs/Data/rpi/qt6 .
Then after build and install I am just doing qt-cmake-private . && ninja && cmake --install . for modules like qtdeclarative, qtshadertools, qtquicktimeline, qtquick3d, qtquickcontrols2. The mentioned modules all build fine, except qtquickcontrols2, which fails with the following. I was using the HEAD of qtdeclarative and qtquickcontrols2 from 12/08.

This used to build fine a week ago. So perhaps something changed around QmlTools in declarative?
It could be something on my side as well. But as far as I can recall it was a clean build, with all modules purged, the staging install dir was removed, etc.
