Answer 1

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

Answer 2

For Alpine Linux:

apk add openssl-dev

Answer 3

On CYGwin, you can install this as a typical package in the first screen. Look for

libssl-devel
