How to Qt cross develop with CLion on remote

This is my first post.
Please forgive any unfamiliarity.

I am building and cross developing a Qt library for PinePhone / Raspberry Pi.
This post describes the procedure for cross-developing Qt in CLion.
(x86_64 <--> AArch64)

This article requires that you have already built and installed the x64 - AArch 64 Qt 6 library.

If you have any problems with this posting, please let me know.
