According to the OpenSSL documentation HMAC_CTX_new() and 
HMAC_CTX_free() were introduced in 1.1.0.
Presumably your OpenSSL version is older than that and disabling OpenSSL 
(presuming you don't need it) or building against a newer version should 
help.

To disable OpenSSL e.g. "cmake ... -DCMAKE_USE_OPENSSL=false" or 
"bootstrap ... --  -DCMAKE_USE_OPENSSL=false".
To point CMake at a custom OpenSSL installation instead setting the 
CMAKE_PREFIX_PATH environment to the installation should work.
