How to resovle dependencies names between Debian and Buildroot?

Question

We have a running app with nodejs and @abandonware/noble package on Radxa Zero with DietPi OS (Debian) which controls a bluetooth device. The documentation of the package says you need sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev. These are Debian packages. What is the equivalent name of these in buildroot?. How can I make sure these Debian packages are installed in my Buildroot image. So far I checked everything for bluez-tools, bluez-utils in Target packages for my image. I can scan and find my BLE device with bluetoothctl and hcitool lescan. When executing on my image the application fails with a similar failure when dependencies are missing.

# NOBLE_HCI_DEVICE_ID=1 node .

internal/modules/cjs/loader.js:1144
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Currently running node 14.20.1.

Strange output of bluemoon. Is this relevant?

# bluemoon 
Bluemoon configuration utility ver 5.65

I think https://github.com/buildroot/buildroot/blob/master/package/bluez5_utils-headers/bluez5_utils-headers.mk is the package that contains the needed headers that you need when including libbluetooth headers that are needed to build native modules.

In any case, I can recommend https://github.com/Emill/node-ble-host instead of noble. This package implements more features and is supposed to be much more stable and bug-free; it's also not "abandoned"... (I am the author of this package).
