Nordic nrf_dm sample does not build

Question

I checked out the nrf github repo and tried to build the nrf_dm sample for the nRF 52840 dev kit which is what I have 
 In VSCode I chose "Add an existing application" and selected the nrf_dm sample directory Then selected the nrf52840dk_nrd52840 from the "Add build configuration" screen but the build fails with the following - see below 
 I did not modify anything.VSCode toolchain is Zephyr 1.9.1 SDK 
 Here is the build output 
 
 Any ideas why it's failing? 
 Thanks 
 Andy

OK, got it to build

Had to make the following changes with 1.9.1 Zephyr SDK

1.Replace CONFIG_DM_MODULE and CONFIG_DM_MODULE_LOG_LEVEL_DBG

with

CONFIG_NRF_DM=y and CONFIG_NRF_DM_LOG_LEVEL_DBG=y

2, Remove "zephyr" subpath from all includes i.e

#include <zephyr/kernel.h> becomes

#include <kernel.h>

3, There are still errors in pwm_led.c but I didn't care about LED's and just commented everything out
