Code:
Building: /usr/bin/ld: /tmp/ccJn0HdJ.o: undefined reference to symbol 'EVP_aes_256_cbc'
/usr/bin/ld: note: 'EVP_aes_256_cbc' is defined in DSO /lib64/libcrypto.so.10 so try adding it to the linker command line
/lib64/libcrypto.so.10: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make: *** [all] Error 1

Keep it in mind: you'll face that kind of errors when the linker cannot find a reference to a symbol, but find a library containing it.
You need to add the path to the library and, eventually, the pkg-config flag.
In fact if you run pkg-config --libs libcrypto you get the flags for the libs to add! :)
To get the respective clfags, instead, you can run pkg-config --cflags libcrypto (in this case none are required)
