I am attempting to compile the peripheral_uart example targeting nrf52840dk, I've done quite a bit of work with zephyr but never with the nRF Connect SDK. I've encountered this on two different systems -- Manjaro and Ubuntu 22.04. After following the steps at https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html and get the following error
dan@dan-MS-7C02:~/nrfbuild/nrf/samples/bluetooth/peripheral_uart$ west build -b nrf52840dk_nrf52840

This looks like an issue linking against the SDKs dynamic libraries, but when I add them to the path it shows up as the wrong version (v3.8.2 vs 3.10)
