How to fix openssl error when including my library

The error he gives me is this:

  

|| === Build: Debug in cheke (compiler: GNU GCC Compiler) === |   main.cpp | 15 | fatal error: openssl / md5.h: No such   file or directory | || === Build failed: 1 error (s), 0 warning (s) (0   minute (s), 0 second (s)) === |

However, I included it in the following way:

#include <openssl/md5.h>
#include <openssl/des.h>

Still, it keeps giving me error and without recognizing it. I'm using the mingw compiler and it's supposed to be for my mingw since I downloaded it for mingw. Someone knows how it could be solved or what the problem is. Anything I can contribute to detail more.

I'm doing from console and with ide, the ide that I use is codeblocks but it does not have much to do. I still have the same problem.

Capture: Current error:
