heartrate server example not building with R

I installed the Qt 5.14 RC packages and I am using Qt Creator 4.11 RC. Note that I can observe the same problem when I use my own Qt 5.14 HEAD build from yesterday (3.12.19) too. My dev environment is Linux. I am using NDK 20b and have All Android versions up to 10 installed in my SDK.

I am trying to build and deploy the bluetooth/heartrate-server examples. The build process stops with

No platform plugin, neither libqtforandroid.so or libqtforandroidGL.so, included in package. Please include one.

It seems that the dependency walk in androiddeployqt is not done properly. This app is not a GUI app but even adding additional dependencies to the project file (e.g. widgets or gui) makes no difference. This was working in prior Qt versions.

I have attached a more complete build output.
