Build log

I'm struggling to build kirigami-gallery for Android. Desktop build works fine, but Android build ends with error:

=====
CMake Error at src/CMakeLists.txt:52 (find_package):
  By not providing "FindKF5Kirigami2.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "KF5Kirigami2", but CMake did not find one.

  Could not find a package configuration file provided by "KF5Kirigami2" with
  any of the following names:

    KF5Kirigami2Config.cmake
    kf5kirigami2-config.cmake

  Add the installation prefix of "KF5Kirigami2" to CMAKE_PREFIX_PATH or set
  "KF5Kirigami2_DIR" to a directory containing one of the above files.  If
  "KF5Kirigami2" provides a separate development package or SDK, be sure it
  has been installed.
=====

Yes, kirigami2-dev package is installed and the "missing" file is in
/usr/lib/x86_64-linux-gnu/cmake/KF5Kirigami2/KF5Kirigami2Config.cmake
Setting KF5Kirigami2_DIR env variable or appending CMAKE_PREFIX_PATH doesn't seem to work. Sorry if this is a trivial CMake issue, I've been using qmake so far.

I already had to work around bug https://bugs.kde.org/show_bug.cgi?id=430952
by commenting out both lines mentioning "NATURAL" in /usr/share/ECM/toolchain/Android.cmake

I'm using Qt 5.15.1 installed in /home/wincak/Qt-toolkit by Qt maintenance tool. Android SDK+NDK are in /home/wincak/Android (Installed automatically by QtCreator. Building non-kirigami Qt applications for Android in QtCreator works)
Building in terminal by following the commands from project's README:

=====
export ANDROID_NDK=/home/wincak/Android/Qt/android-sdk-tools/ndk/21.3.6528147
export ANDROID_SDK_ROOT=/home/wincak/Android/Qt/android-sdk-tools
export Qt5_android=/home/wincak/Qt-toolkit/5.15.1/android
export PATH=$ANDROID_SDK_ROOT/platform-tools/:$PATH
# adapt the following path to your ant installation
export ANT=/usr/bin/ant
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

mkdir build
cd build

Kirigami guys, could you set up a CI that would build at least a minimal example on Ubuntu/Neon for Android, where could we noobs see all the necessary build steps? Build logs on binary-factory.kde.org give only hints, not the whole thing.
