Unable to build the external delegate for the A311D processor on Android armv7-a #171
Description
If I understand correctly I can build an External Delegate (for example: libvx_delegate.so) via this repository and run TensorFlow Lite models on the NPU of the A311D processor?
My first question, do I need to modify TensorFlow Lite to run this delegate, or can I swap this delegate with a different external delegate with a pre-build TensorFlow Lite plugin?
For example replace the external delegate on this location with the libvx_delegate.so (this runs TensorFlow Lite):

My second question is, I'm unable to build this external delegate:

It fails with the following output:
