don't compile on ubuntu 14.04

[fabiostrada77]

sscep don't compile on ubuntu 14.04. I executed these commands:

1. I executed ./Configure
2. I installed openssl from https://github.com/openssl/openssl
3. I Modified the OPENSSL reference into the Makefile with path of my openssl
4. I executed make
   I had these errors:

The build system and build instructions have been greatly improved since 2017, so I am closing this.
