Issues with compiling with openssl for mac based platforms

[fred-dev]

I am having issues compiling Poco for mac platforms (my end goal is macos (x86 and arm64) and iOS and iOS Simulator (x86 and arm64).

To achieve this I am first compiling openSSL (seems it is all working ok), and then passing the path to cmake. However I cannot get Poco to compile with openSSL and get a number of errors from Crypto/src/ECKeyImpl.cpp and Crypto/src/EVPPKey.cpp:

error: use of undeclared identifier 'PEM_read_PrivateKey'
error: use of undeclared identifier 'PEM_read_PUBKEY'

I'm using Poco 1.14.2 and openSSL 1.1.1q (I had similar issues with 3.2.1)

I'm using CMake with these flags:
-DPOCO_STATIC=ON -DPOCO_UNBUNDLED=OFF -DENABLE_CRYPTO=ON -DENABLE_NETSSL_OPENSSL=ON

Is there a specific version of openSSL I need to use? Or Specific compiler flags I need for either openSSL or Poco to make this work?

OpenSSL installed with homebrew works fine.

Where did you obtain OpenSSL from?

I had thought I would need to compile OpenSSL for each platform I wanted to compile Poco for, so I downloaded OpenSSL from GitHub and created a script to compile it for my target platforms. If I do not need to do this and can generate the Poco libs for example for iOS using the homebrew installation on my x86 mac that is great, but I guess I then just misunderstood the capabilities of the build system.
