Compiling error on Ubuntu 20.04

[j75]

Hello! I'm encountering the following error on Ubuntu 20.04.3 LTS:

.../src/IO/CNetBlockIO.cpp:101:47: error: ‘boost::asio::ssl::stream<boost::asio::basic_stream_socket<boost::asio::ip::tcp> >::lowest_layer_type’ {aka ‘class boost::asio::basic_socket<boost::asio::ip::tcp, boost::asio::executor>’} has no member named ‘native’
  101 |     int ret = setsockopt(sctrl.lowest_layer().native(), SOL_SOCKET, SO_PRIORITY, &priority, sizeof(priority));
      |                                               ^~~~~~

Any idea how to fix that? (a missing dependency?) cmake show that initially:
