Apple deprecated openssl a while back. The recommend change was to use their common crypto library. I found the following man page:

man CC_crypto

The openssl header files ARE NOT in the normal usr/include/ MacOSX10.11.sdk location. They are in the Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift-migrator/sdk/MacOSX.sdk/usr/include directory. However this does not appear to be in the normal search path.

Any ideas how to proceed?
