What is arduino-cmake?

Arduino CMake lets you build and upload code for Arduino boards without using the standard Arduino software interface. It gives you the freedom to use your preferred code editor and command-line tools, which is ideal for people who find the default Arduino environment too limiting. Normally, writing code for an Arduino requires using the official application to compile and send your program to the physical board. This project replaces that application with a widely-used, standard build tool called CMake. Because CMake is flexible, it can automatically translate your code into the specific format an Arduino needs, and it works across Windows, Mac, and Linux. From there, you can use simple terminal commands to turn your code into a working program and send it to the board. This tool is built for people who are comfortable writing code but want to work with Arduino hardware. For example, a software engineer building a custom home automation device might already use a professional code editor and a command-line workflow for their daily work. Instead of completely switching gears and opening the basic Arduino app just to manage their hardware project, they can stay in their preferred environment. They can also generate project files for major development software like Eclipse, XCode, or Visual Studio. The system handles practical details behind the scenes. It automatically detects standard Arduino add-on libraries, supports all official Arduino boards, and can even set up a serial terminal connection so you can read live data from the board while it runs. The README doesn't go into detail on how to use every single feature, but it makes clear that the goal is to give builders full control over the entire process.
