C++23 program deploy test (runs on any Linux distro)

This is a test C++ program, compiled on my latest Arch Linux, used a fancy C++23 feature std::println to say hello world.
Without mockup, it's definitely not runnable on very old Linux distro (e.g. CentOS and Ubuntu 18.04), right?
I packed it with the mockup tool. Download it and see if it can runs correctly on your whatever Linux distributions.

tar zxvf cpp23test.tgz
cd cpp23test
./cpp23.sh

It should prints hello from C++23.
