VS Code Raspberry Pi Pico W C SDK: how to specify inlcudes?

Question

I'm pretty new to Raspberry Pi Pico. I am using Windows 10.

I installed all neccesary stuff (Visual Studio Code, CMake, compiller, etc.) using executable from here.

I buit example projects from there, but there was no pico_w folder.

I went to https://github.com/raspberrypi/pico-examples and download all example projects, inclunding pico_w and just replaced with my current pico-examples folder.

I also did the same for SDK (download folder from GitHub and replace current one with it).

Then I restarted VS Code, switched to "Cmake" extension tab, pressed "Configure All Projects", however there was no pico_w element in the list, although in "Explorer" tab, of the project folder, of course it was.

Then I copied pico_w\wifi\access_point folder to hello_world, just near serial and usb folders.

After that, it started to be displayed at CMake list, however can't be compiled, becuause it can't find most of include header, such as pico/cyw43_arch.h, lwip/pbuf.h, dhcpserver.h.

Project without that headers sucessfully complies.

What am I doing wrong?

I added "PICO_BOARD": "pico_w" in .vscode/setting.json, now, in CMakeLists.txt PICO_CYW43_SUPPORTED is true, however, NOT TARGET pico_cyw43_arch is also true.

So, what is TARGET and how do I make it be pico_cyw43_arch?

Current CMakeLists.txt

cmake_minimum_required(VERSION 3.13)

# initialize the SDK directly
include("C:/Program Files/Raspberry Pi/Pico SDK v1.5.1/pico-sdk/pico_sdk_init.cmake")

project(pico_examples C CXX ASM)
set(CMAKE_C_STANDARD 11)
set(CMAKE_CXX_STANDARD 17)

if (PICO_SDK_VERSION_STRING VERSION_LESS "1.3.0")
    message(FATAL_ERROR "Raspberry Pi Pico SDK version 1.3.0 (or later) required. Your version is ${PICO_SDK_VERSION_STRING}")
endif()


# initialize the Raspberry Pi Pico SDK
pico_sdk_init()

include(example_auto_set_url.cmake)

add_compile_options(-Wall
        -Wno-format          # int != int32_t as far as the compiler is concerned because gcc has int32_t as long int
        -Wno-unused-function # we have some for the docs that aren't called
        )
if (CMAKE_C_COMPILER_ID STREQUAL "GNU")
    add_compile_options(-Wno-maybe-uninitialized)
endif()

set(PICO_BOARD pico_w)

# rest of your project
add_subdirectory(pico_w)


add_executable(wifi
    pico_w/wifi/access_point/picow_access_point.c
)

# Add pico_stdlib library which aggregates commonly used features
target_link_libraries(wifi pico_stdlib
pico_cyw43_arch_lwip_poll # we need Wifi to access the GPIO, but we don't need anything else
hardware_flash
hardware_irq
hardware_adc
hardware_pwm
hardware_i2c
hardware_spi
hardware_dma
hardware_exception)

# create map/bin/hex/uf2 file in addition to ELF.
pico_add_extra_outputs(wifi)

Current project tree

pico_w -> wifi -> access_point    -> dhcpserver -> ...
|       |        |                -> dnsserver -> ...
|       |        |                -> CMakeLists.txt
|       |        |                -> lwipopts.txt
|       |        |                -> picow_access_point.c
|       |        -> CMakeLists.txt
|       |        -> lwipopts_examples_common.h
|        -> CMakeLists.txt
CMakeLists.txt (content above)
exemaple_auto_set_url.cmake

Content of wifi folder just from GitHub. Also there is .vscode folder, with setting.json where I put:

{
    "files.associations": {
        "dhcpserver.h": "c"
    },
    "cmake.configureSettings": {
        "PICO_BOARD": "pico_w",
        "TARGET": "access_point",
        "DPICO_CYW43_SUPPORTED": 1
    }
}

Update

Seems, like "submodules" are not initizalied:

[cmake]   cyw43-driver submodule has not been initialized; Pico W 
wireless support will be unavailable
[cmake]   hint: try 'git submodule update --init' from your SDK directory

What exactly should I do? Just running that command it from cmd or PowerShell does not work
