What is your OpenSSL version?

I got the same error on Ubuntu 16.04, I have got this ssl dev package installed from Ondřej Surý which is very common for using php.

root@ubuntu:~# aptitude show libssl-dev
Package: libssl-dev

Description: Secure Sockets Layer toolkit - development files
 This package is part of the OpenSSL project's implementation of the SSL and TLS cryptographic protocols for secure
 communication over the Internet. 

 It contains development libraries, header files, and manpages for libssl and libcrypto.

how to compile with that version?

It would be great if the build process checked for the right OpenSSL version and gave some hints if the installed version is not the one required.

Thank you very much for your attention!

Qt SDK does not support OpenSSL 1.1.x, you need to use OpenSSL 1.0.X 1.0.x is not old, both 1.1.x and 1.0.x in active development.

How to use openssl 1.0.x instead of default 1.1.x?

[JulyIghor]

install package libssl1.0-dev
