esp-at: Build failed when enabled ethernet

I’m trying to build a custom AT command firmware to enable Ethernet. I set it like this in menuconfig. Component Config->AT->AT Ethernet Support [*] If you do not check AT ethernet support, the build will succeed, but if you check it, the build will not be possible.

esp-at repository version:

~/esp-at$ git log -n 1 --format=%H
a1f3fc0c45d3935e99e52c44bd98b2eb5bd63c95

Build logs:

module_name WROVER-32
platform_name=ESP32,module_name=WROVER-32
Checking Python dependencies...
Python requirements from /home/ubuntu/esp-at/esp-idf/requirements.txt are satisfied.

@katodo @jitenshap Here is a workaround for AT ethernet compile. Please modify: https://github.com/espressif/esp-at/blob/master/components/at/CMakeLists.txt#L3 to

    bootloader_support app_update openssl wpa_supplicant spi_flash main)

That is, appending the libmain.a to at core require_components, so that libesp*at.a can link to implement of esp_at_get_eth_default_config, which defined in libmain.a.

At the same time, esp-at will simply and adjust the directory structure to facilitate reasonable code management.
