Compile Erlang 24.2 for iOS on mac system

Hey!

I applied the patch in socket_util.c, but now I am getting the following error "

Undefined symbols for architecture arm64:"_BN_CTX_free", referenced from:"

I configure the otp_build script the following ... in /ios/openssl/ is the compiled openssl version 1.1.1k for ios build.
./otp_build configure --xcomp-conf=./xcomp/erl-xcomp-arm64-ios.conf --with-ssl=/Users/michael/Entwicklung/compile/ios/openssl/

Also i compiled OpenSSL 1.1.1k for the cross build, also applied with a patch to get it compiled.

See below the whole output, any hints?
