CMAKE Esp32 using azure iot samples - what to check in into my repository

Question

I am really new to iot/embedded world (I come from the b2b java world). Currently I am starting setting up an ESP32 based project. So far I tried esp-idf Hello World example, went through Platform IO tutorial and tried the Azure-IOT-Esp32-Sample. I would stick with the latter one because I got out of the box connection to azure and MQTT - this is what I need at the end.

As stated in readme I recursively checked out

cd iot-middleware-freertos-samples
git submodule update --init --recursive

What gives me a bunch of stuff. The question is what do I need to put into my repository?

• is it enough to check in all in \iot-middleware-freertos-samples\demos\projects\ESPRESSIF\esp32?
• what else I need to check in?

The goal is of course: if I clone this repo it should build out of the box - and download/clone/ generate all stuff needed.

is it enough to check in all in \iot-middleware-freertos-samples\demos\projects\ESPRESSIF\esp32?

No, since you will need to have the libraries that are at the root of the github repo. Check for example the CMakeLists.txt file inside the folder iot-middleware-freertos-samples/demos/projects/ESPRESSIF/esp32/components/azure-iot-middleware-freertos/

It tells CMAKE to look for the libraries in the Root Path

set(ROOT_PATH
    ${CMAKE_CURRENT_LIST_DIR}/../../../../../..
)

So, you will need to check every CMakeLists.txt file in the ESP32 Project folder and decide what you can remove or not from the clone you did.
