Using

platform = ststm32@17.0.0
board = lora_e5_dev_board
framework = arduino

with empty sketch

#include <Arduino.h>

void setup() {}
void loop() {}

fails to compile

Because even though the board says it wants to use the "variant_generic.h"

it does not activate the right macro to enable the code to be compiled

https://github.com/stm32duino/Arduino_Core_STM32/blob/586319c6c2cee268747c8826d93e84b26d1549fd/variants/STM32WLxx/WL54JCI_WL55JCI_WLE4J(8-B-C)I_WLE5J(8-B-C)I/variant_generic.cpp#L13-L17

This, it needs an additional

build_flags = -DARDUINO_GENERIC_WLE5JCIX

to work properly.
