CONF_MODULE undefined?

[Blumenthal, Uri - 0553 - MITLL]

I hit this problem recompiling libp11 with the current OpenSSL-3.0 master. It's on MacOS Catalina 10.15.4 with the latest Xcode-11.4.1, but I think that's irrelevant. I checked through all the .h files in the OpenSSL sources, and found no definition o CONF_MODULE. OpenSSL-3.0 is installed into /Users/ur20980/openssl-3 (as is obvious from the following).

Here are the errors:
