wtf is lvgl?

This repository is a version of LVGL (Light and Versatile Graphics Library) set up to build using the Zig build system (v0.11.0). LVGL is a popular, free, open-source toolkit for creating graphical user interfaces on embedded hardware. If you are building a device with a screen, like a smartwatch, a thermostat, or a small handheld gadget, this library gives you the buttons, sliders, charts, and text elements you need to make it look polished and professional. At its core, LVGL is a C library that runs on very modest hardware. You only need 32 kB of RAM and 128 kB of storage to run it, which means it works on small, inexpensive microcontrollers rather than requiring a full computer processor. The library handles drawing the UI, managing touch or button inputs, and even rendering text in multiple languages. This specific repo makes it possible to compile all of that using the Zig build tool, which is an alternative way to manage how code is assembled into a final application. The people who would use this are developers building screens into physical products. For example, a startup making a smart home device with a small touchscreen could use LVGL to design the interface. It works with many common display types (OLED, TFT, ePaper) and is already integrated into popular hardware platforms like ESP32 and Arduino. There is also a drag-and-drop editor called SquareLine Studio that helps you design the interface visually without writing all the code by hand. One notable thing about this project is that the library itself has no required external dependencies and does not force you into a specific build system. It is designed to be portable across different operating systems and hardware setups. This repo specifically demonstrates that flexibility by adding Zig build support on top of the standard C and CMake options that the main LVGL project already provides.
