1. Xmake is a cross-platform build utility based on the Lua scripting language.
2. Xmake is very lightweight and has no dependencies outside of the standard library.
3. Uses the `xmake.lua` file to maintain project builds with a simple and readable syntax.
Xmake can be used to directly build source code (like with Make or Ninja), or it can generate project source files like CMake or Meson. It also has a built-in package management system to help users integrate C/C++ dependencies.
