The error: cannot find -lc++ using ndk r20 can be solved like this: https://codereview.qt-project.org/c/qt/qtbase/+/264903/9/mkspecs/android-clang/qmake.conf#34

For example to compile for android armv7 ndk r20, locate the file: C:\Qt\5.13.0\android_armv7\mkspecs\android-clang\qmake.conf and add the missing -nostdlib++ for android x86 (i use this for emulator), locate the file: C:\Qt\5.13.0\android_x86\mkspecs\android-clang\qmake.conf

According to this page installing ndk version 19 should fix it. Did it for me.
