Question/Issue:
[Describe the question or issue in detail]
The build fails when trying to deploy Edge-impulse model to ESP32s3 based custom PCB.
Project ID:
[793647]

Context/Use case:
Use case is using Microphone to sample and train data and then deploy the model

Summary:
[Provide a concise summary of the bug]
I have copied the standalone application template for esp32 idf environment. The issue that I am running into is during the build process of the application.
The project fails to build
