* Xtensa toolchain declares `int32_t` as `int` but RISC-V toolchain
* declares `int32_t` as `long int` which causes compilation errors.
*
* See:
* https://github.com/espressif/esp-idf/issues/6906
* https://github.com/espressif/arduino-esp32/issues/5086

* You need to add the following lines in `build_flags`:
* -I$PROJECT_DIR/include
