        Hi, I have reviewed the light_bulb app code in NCS2.8.0(include src code/CMakeLists.txt/prj.conf and so on)。
        But I can't find where the path of matter is included, could you please tell me?

        Yes, I have found it, but I don't know how the project(ex: light_bulb) include the matter path, Could you answer this question?

[Sigurd Hellesvik]

That is an unusual question. Maybe it helps for me to know the context. What are you trying to do that makes you need this path?

        I want to create a project in NCS2.8.0, while my cmake file as blow:

        

cmake_minimum_required(VERSION 3.13.1)

# Set Zephyr project
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(my_matter_project)

# Set Matter SDK path
set(MATTER_SDK_DIR /path/to/matter)

# Include Matter CMake file
include(${MATTER_SDK_DIR}/config/nrfconnect/app/CMakeLists.txt)

# Add source file
target_sources(app PRIVATE src/main.c)

        But when I build this demo, it popup "undefined CONFIG_CHIP", so I think I have not add matter code to my project.

        Could you give me some help? thx

Our Matter samples does not use this cmake file, so I do not think it is generally needed for Matter. You see they enable CONFIG_CHIP in prj.conf.

If you still want to set this MATTER_SDK_DIR we can try to make that work?
Just one thing first: I cannot find the CMakeLists.txt file you are referring to: https://github.com/nrfconnect/sdk-connectedhomeip/tree/master/config/nrfconnect/app.
