How to build and change the latest core sources?

Official Hardware UNO Family UNO R4 WiFi
2

I don't have it fully building a sketch yet with the github code... But getting closer.
Note I am running windows 11.

What I have done so far:
I found you need to clone the project recursively:git clone --recursive GitHub - arduino/ArduinoCore-renesas

That was not unexpected. But then found there were some form of Sybolic links built into the project. That were showing up as a file that only contained a relative pathname to a another file or directory... Several internet searches later found, I probably needed to reinstall git and enable one of the advanced options for symbolic links... So installed 2.41....

One of the places I saw mentioned maybe telling the clone to enable symbolic links.
So I recloned again:
git clone --recursive -c core.symlinks=true GitHub - arduino/ArduinoCore-renesas

This failed:

More search found, I need to change my user settings to enable developer mode.

I redid the same clone and this time that worked.
Note: I found I had to redo the core\arduino\api link as to how and where I cloned things to.

Now build gets farther, but failing with:
