Allow setting additional CLI arguments

README.md

@@ -83,6 +83,7 @@ This extension provides several commands in the Command Palette (<kbd>F1</kbd> o
 | `arduino.useArduinoCli` | Whether to use the Arduino CLI (`true`) or the legacy Arduino IDE (`false`) -- defaults to `false`. If using `true`, either leave the `arduino.path` and `arduino.commandPath` values unset to use the bundled version of Arduino CLI, or point them at a custom version of Arduino CLI. Note that a future version of the extension will change this default to `true` and remove support for legacy Arduino IDE. |
 | `arduino.path`  | Path to the Arduino installation.  You can use a custom version of Arduino by modifying this setting to include the full path. Example: `C:\\Program Files\\Arduino` for Windows, `/Applications` for Mac, `/home/<username>/Downloads/arduino-1.8.1` for Linux. (Requires a restart after change). The default value is automatically detected from your legacy Arduino IDE installation path. To use the Arduino CLI, use the path that contains the `arduino-cli` executable (e.g. `/usr/local/bin`), or leave it unset to use the bundled version of Arduino CLI. |
 | `arduino.commandPath` | Path to an executable (or script) relative to `arduino.path`. The default value is `arduino_debug.exe` for Windows, `Contents/MacOS/Arduino` for Mac and `arduino` for Linux, You also can use a custom launch script to run Arduino by modifying this setting. (Requires a restart after change) Example: `run-arduino.bat` for Windows, `Contents/MacOS/run-arduino.sh` for Mac and `bin/run-arduino.sh` for Linux. To use the bundled version of Arduino CLI, leave this option unset. To use a custom version of Arduino CLI, use `arduino-cli`. |
+| `arduino.additionalCliArguments` | Additional arguments to append at the tail of the build command. |
 | `arduino.additionalUrls` | Additional Boards Manager URLs for 3rd party packages as a string array. The default value is empty. |
 | `arduino.logLevel` | CLI output log level. Could be info or verbose. The default value is `"info"`. |
 | `arduino.clearOutputOnBuild` | Clear the output logs before uploading or verifying. Default value is `false`. |
