connectedhomeip: compile lighting-app/nrfconnect example failed

I try to compile the latest commit 8d7486f in ubuntu 20.04 LTS, as in the README , I use the ‘native shell setup’, compiled this example but got the following error (west build -b nrf52840dk_nrf52840 -t menuconfig also report the same error):

root@ubuntu:# export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb

root@ubuntu:# west build -b nrf52840dk_nrf52840
WARNING: ZEPHYR_BASE=~/work_src/ncs/zephyr in the calling environment will be used,
but the zephyr.base config option in ~/work_src/connectedhomeip/examples/lighting-app/nrfconnect is "zephyr"
which implies a different ZEPHYR_BASE=~/work_src/connectedhomeip/examples/lighting-app/nrfconnect/zephyr
To disable this warning in the future, execute 'west config --global zephyr.base-prefer env'
