CMake: Failed to find required Qt component "ProtobufQuick".

I came across this problem when adapting a project that use QT gRPC to 6.8.0 beta1 and trying to build it under Android x86_64

Project url: https://github.com/jgaa/next-app

[cmake] Running /usr/bin/cmake -S /home/jgaa/src/next-app/src/NextAppUi -B /var/local/build/NextAppUi-Android_Qt_6_8_0_Clang_x86_64-Debug in /var/local/build/NextAppUi-Android_Qt_6_8_0_Clang_x86_64-Debug.
[cmake] – Could NOT find Qt6ProtobufQuick (missing: Qt6ProtobufQuick_DIR)
[cmake] CMake Error at CMakeLists.txt:37 (find_package):
[cmake] Found package configuration file:
{{[cmake] }}
[cmake] /opt/Qt/6.8.0/android_x86_64/lib/cmake/Qt6/Qt6Config.cmake
{{[cmake] }}
[cmake] but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
[cmake] FOUND. Reason given by package:
{{[cmake] }}
[cmake] Failed to find required Qt component "ProtobufQuick".

[cmake] Expected Config file at
