      Description

      Hello

      I just did try to build and run SSL Websocket client and server from provided examples

      When both client and server start such messages in terminal

      qt.network.ssl: QSslSocket: cannot resolve sk_value
      qt.network.ssl: QSslSocket: cannot resolve SSL_library_init
      qt.network.ssl: QSslSocket: cannot resolve SSL_load_error_strings
      qt.network.ssl: QSslSocket: cannot resolve SSL_get_ex_new_index
      qt.network.ssl: QSslSocket: cannot resolve SSLv3_client_method

      qt.network.ssl: QSslSocket: cannot resolve SSLv3_server_method
      qt.network.ssl: QSslSocket: cannot resolve SSLv23_server_method
      qt.network.ssl: QSslSocket: cannot resolve X509_STORE_CTX_get_chain
      qt.network.ssl: QSslSocket: cannot resolve OPENSSL_add_all_algorithms_noconf
      qt.network.ssl: QSslSocket: cannot resolve OPENSSL_add_all_algorithms_conf
      qt.network.ssl: QSslSocket: cannot resolve SSLeay
      qt.network.ssl: Incompatible version of OpenSSL
      SSL Echo Server listening on port 1234
      
      

      Both unmodified project did build just fine. Here are all ssl installed packages

      libcurl4-openssl-dev/bionic-updates,bionic-security,now 7.58.0-2ubuntu3.5 amd64 [installed]
      libio-socket-ssl-perl/bionic,bionic,now 2.056-1 all [installed]

      openssl/bionic-updates,bionic-security,now 1.1.0g-2ubuntu4.1 amd64 [installed]
      perl-openssl-defaults/bionic,now 3build1 amd64 [installed]
      ssl-cert/bionic,bionic,now 1.0.39 all [installed]
      
      

      After starting ssl server and client I do not see connection made or any other error except what is above. Is there a work around for openssl 1.1.0g which is default ssl library on Ubuntu 18.04? Does this work in upcoming 5.12?
