Description
Sometimes, but not everytime I have random configure errors when building an Android example this way.
/usr/lib/aarch64-linux-gnu/qt-android-6.8-arm64-v8a/bin/qt-cmake '-DQT_ANDROID_ABIS=arm64-v8a;x86_64' -DQT_PATH_ANDROID_ABI_arm64-v8a=/usr -DQT_ANDROID_PATH_CMAKE_DIR_arm64-v8a=/usr/lib/aarch64-linux-gnu/qt-android-6.8-arm64-v8a/cmake -DQT_PATH_ANDROID_ABI_x86_64=/usr -DQT_ANDROID_PATH_CMAKE_DIR_x86_64=/usr/lib/x86_64-linux-gnu/qt-android-6.8-x86_64/cmake -DANDROID_SDK_ROOT=/usr/lib/android-sdk -DANDROID_NDK_ROOT=/usr/lib/android-ndk -DQT_ENABLE_VERBOSE_DEPLOYMENT=ON -DCMAKE_VERBOSE_MAKEFILE=ON -G 'Unix Makefiles' -S qtbase/examples/corelib/platform/androidnotifier -B /home/debci/androidnotifier/cmake-multi-build + cmake --build /home/debci/androidnotifier/cmake-multi-build --parallel

I face this with 6.7 also
It seems to affect only multiabi builds when generator is "Unix Makefile". When it is set generator to Ninja, I haven't faced these random errors yet.
