Description
I'm building Qt 6.2.3 on Ubuntu 20.04 x86_64 for the host and for Android. I use a number of external third-party dependencies like libpng, libtiff, libjpeg-turbo, and ICU. This usually works fine on the host. In the Android-build I can see that after cmake configure, Qt reports that all these system libraries have been found, including ICU. However in the final APK package, the ICU libraries are missing. Also the application fails to start in the Android device. When I check the Android logs, I can see the following error:

The "interesting" part seems to be the library names for ICU: For example "libicui18n.so.so" (with duplicate "so"-suffix).
In my library installation directory, the ICU libraries have the "correct" names:
lrwxrwxrwx 1 user user 18 Feb 26 09:20 libicudata.so -> libicudata.so.70.1 lrwxrwxrwx 1 user user 18 Feb 26 09:20 libicudata.so.70 -> libicudata.so.70.1 -rwxr-xr-x 1 user user 29467752 Feb 26 09:20 libicudata.so.70.1 lrwxrwxrwx 1 user user 18 Feb 26 09:20 libicui18n.so -> libicui18n.so.70.1 lrwxrwxrwx 1 user user 18 Feb 26 09:20 libicui18n.so.70 -> libicui18n.so.70.1 -rwxr-xr-x 1 user user 4161144 Feb 26 09:20 libicui18n.so.70.1 lrwxrwxrwx 1 user user 16 Feb 26 09:20 libicuio.so -> libicuio.so.70.1 lrwxrwxrwx 1 user user 16 Feb 26 09:20 libicuio.so.70 -> libicuio.so.70.1 -rwxr-xr-x 1 user user 106456 Feb 26 09:20 libicuio.so.70.1 lrwxrwxrwx 1 user user 16 Feb 26 09:20 libicuuc.so -> libicuuc.so.70.1 lrwxrwxrwx 1 user user 16 Feb 26 09:20 libicuuc.so.70 -> libicuuc.so.70.1 -rwxr-xr-x 1 user user 2484304 Feb 26 09:20 libicuuc.so.70.1
I can confirm that when I manually copy the above libraries into $ANDROID_PACKAGE_SOURCE_DIR/libs/ in the custom package directory with the incorrect names (like "libicui18n.so.so"), the application works.
On the other hand, with the correct ICU library names (like "libicui18n.so"), the application fails to start.
I assume the failing deployment with androiddeployqt is somehow related to the "incorrect" ICU library names?
