Compile failed when adding iotjs external lib for ESP32, even trying to add the xtensa to the target-arch still failed. Please help~ Thanks

    parser.add_argument('--target-arch',
        choices=['arm', 'xtensa', 'x86', 'i686', 'x86_64', 'x64'],
        default=platform.arch(),
        help='Specify the target architecture: '
             '%(choices)s (default: %(default)s)')

@weixiongmei Thank you for the issue. Let me check.

[sunghan-chang]

@weixiongmei Sorry but it needs to be supported by iotjs. That is difficult to be done by us.

[sunghan-chang]

@haesik If possible, could you share the plan to support xtensa architecture with esp32 board on IoT.js project?

[weixiongmei]

@sunghan-chang, I had have port all the ESP32 drivers for Jerryscript, but I couldn't get any success for the iotjs, because I'm not familiar with CMAKE, if anyone can help to get a successful compilation for ESP32, I can help to port all the drivers for it.

@weixiongmei Sorry for late reply. Could you let us know your usages of iotjs? We are working on micropython so that we could manage this. But I can't guarantee it on iotjs.
