Android: multi-abi build fails

This happens for every project I build. Can be reproduced with template of QtQuick application generated by Qt Creator.

Host machine: Linux x86_64
Target: arm64-v8a - builds correctly
Target: armeabi-v7a - builds correctly

Multi-abi settings:
using arm64-v8a as main abi
setting CMake var QT_ANDROID_ABIS = arm64-v8a;arm-v7a
There is small issue with NDK location reported in QTCREATORBUG-27761 but its easy to overcome.
Build stops on CMake error from CMakeList.txt file, when it should find Qt libs:

find_package(Qt6 COMPONENTS Quick REQUIRED):

And the error message is:

Could not find a configuration file for package "Qt6" that is compatible
  with requested version "".

  The following configuration files were considered but not accepted:

    /my-path-to-qt/6.3.1/android_armv7/lib/cmake/Qt6/Qt6Config.cmake, version: 6.3.1 (32bit)

This file is exactly the version that should be used for armeabi-v7a build but for some reason CMake rejects it.

I tested the same scenario with Qt 6.3.0 with the same result.
