On step 11 ./script/build nrf52840 UART_trans throws an error:

So I modified otUdpBind to include netif otUdpBind(aInstance, &sUdpSocket, &listenSockAddr, netif);. and defined it as otNetifIdentifier netif = OT_NETIF_THREAD; per cli_udp.cpp (just copying that as an example of what to add for that argument

[85/85] Linking CXX executable bin/ot-cli-ftd
ninja: build stopped: subcommand failed.

The headers are included and these commands do appear to be defined in the repo. I'm stuck at this point. Please advise.

I just posted the following response in openthread/openthread#7056:

We plan to address this as part of openthread/ot-docs#43.

Your modification to `otUdpBind()` is correct. However, you also need to disable the `ot-cli-radio` build since `ot-cli-radio` does not provide the necessary APIs.

One way is to try setting `OT_CMAKE_NINJA_TARGET` to `ot-cli-ftd`.
