Write DH key exchange with OpenSSL under Xcode and encounter "Ld:library not found For-lcrypto" issue (Resolved)

This afternoon with Xcode to write a very simple Diffie-hellman key exchange code, reference to a bunch of data, excluding the logic and grammar of the error will still be compiled however, there is a problem, the problem screenshot is as follows:

Always prompt "Ld:library not found For-lcrypto" & "Linker command failed with exit code 1"
