Summary of Changes

Hello @gameknife, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a comprehensive refactoring of the project's core infrastructure. It modernizes the build system for better feature control, automates the acquisition of external libraries, and centralizes rendering visualization settings for improved developer experience. These changes aim to enhance maintainability, simplify development workflows, and lay a stronger foundation for future feature development and debugging.

Highlights

• Build System Refactoring with CMake Presets: The build system has been significantly overhauled to use a new CMake preset structure, introducing 'minimal', 'default', and 'full' feature sets. This allows for more flexible and granular control over enabled features like AVIF, DLSS, OIDN, and QuickJS, simplifying the build process across different platforms.
• Automated External Dependency Management: Manual fetching scripts for external dependencies such as NVIDIA Streamline, Intel OIDN, TypeScript Compiler (TSC), and MoltenVK have been replaced. CMake's FetchContent module now automatically downloads and configures these libraries, streamlining project setup and reducing maintenance overhead.
• Centralized Rendering Show Flags: A new ShowFlags struct has been introduced to centralize various rendering debug and visualization options (e.g., wireframe, debug lighting, bounding boxes). This improves UI consistency, code organization, and simplifies how these flags are accessed and managed throughout the engine and editor.
• Physics System Enhancements: The Jolt Physics integration now includes a new HIDDEN object layer, allowing physics bodies to exist without colliding with moving objects. Physics body management has been improved with a new RemoveBody function and refined SetBodyActive logic, enhancing control over physics interactions.
• Rendering Pipeline Optimizations: The wireframe rendering pipeline has been re-enabled and integrated. Skinned mesh updates are now more efficient, only processing animations that are actively playing and utilizing a request queue to manage model updates, reducing unnecessary computations.

Code Review

This pull request introduces a significant and beneficial refactoring of the build system, migrating to CMake Presets and FetchContent for dependency management. This greatly improves the project's structure, portability, and maintainability. Additionally, the introduction of a ShowFlags struct to separate display-related settings from general user settings is a good architectural improvement. My review includes a few suggestions for code formatting to enhance readability and a critical fix for the build.sh script to ensure its robustness.
