The error suggests that the version of OpenSSL you use does not include _EVP_sha256 and _HMAC.
Unfortunately, I don't have a Mac to test, but searching for this error it seems this is a common (and known) issue:
https://tor.stackexchange.com/questions/595/tor-compiling-error-undefined-symbols-in-libor-crypto-a
In case it is just the test cases that fail and you're not using any of the HS* algorithms in your project you might not need to change anything since the should not trigger a linker error when not used.
If you need HS256, HS384 or HS512 support it looks like your best bet is recompiling OpenSSL.
Please let me know if you solved it so I can add a note in the Readme to inform users about this.

the openssl installed by brew
from jwt-cpp.

@DLTech21 Make sure the version installed by brew is actually used when building and if it is, check if it contains those two symbols. I suspect it is using either the wrong library (i.e. system default, not the brew one) or the brew lib does not contain sha256 support.
I'm sorry for not being really helpful. I'll try to compile it once I have access to a Mac again but it might take until the beginning of next month and really hope to solve this issue long before this time.

I'll add a note to Readme and link this issue in case of somebody running into the same issue.

I was also facing the same issues in mu ubuntu 16.04, resolved it by Including -libssl -llibcrypto dependencies in Makefile
from jwt-cpp.

According to the article, replace brew openssl to the default successfully : https://www.zhihu.com/question/36693783
But the problem still hasn't been solved.

The quiet old CMake 🙈
I would strongly recommend using targets instead like
Line 92 in c9a511f
Should look like this
find_package(OpenSSL REQUIRED)
add_executable(your_app_here main.cpp)
target_link_libraries(your_app_here OpenSSL::SSL OpenSSL::Crypto)from jwt-cpp.

Thanks ! but some error occur as follows when using targets instead, what's other should i do ?
