✨ Highlights of This Branch
This custom branch of LuaJIT 2.1 introduces modern development enhancements and extensibility features:

🔧 CMake Build System
Build LuaJIT using CMakeLists.txt, fully configurable for different platforms and IDEs (e.g., Visual Studio, Ninja, Make).

🧩 Pluggable File I/O Extensions
Override default file operations (fopen, fread, fclose, etc.) by providing custom function implementations. This allows LuaJIT to be embedded in constrained or virtualized environments.

📁 Sample Code Included
Demonstrates how to hook into file I/O or integrate the LuaJIT core using CMake builds.

📄 License
LuaJIT is free software, released under the MIT license.
