+- `lakers-c` library and headers:
+  - either download them from the [releases page on GitHub](https://github.com/openwsn-berkeley/lakers/releases)
+  - or build yourself following the README in the `lakers-c` crate
 - [RIOT](https://github.com/RIOT-OS/RIOT)'s source code must be available in a local folder, which can be set via the `RIOTBASE` variable.
