Hope to provide xmake.lua without relying on cmake

Xmake is also a build system developed by Chinese developers, and I think you can also provide a build configuration file for xmake.

Chinese developers are very good, and xmake is also very easy to use!

I just saw a method that uses the xmake package. However, I still hope to have a configuration file xmake.lua

It seems strange that the libhv package in the xmake repository still relies on cmake. I still hope to provide the xmake.lua file without relying on cmake anymore
