// example_cameras.rs
// A 3D first-person multi-camera example using Bevy 0.15.3 and Bevy Rapier3D 0.28.
// Features multiple players with switchable first-person cameras, mouse capture, WASD movement, Space key jumping, and a debug UI.
// Player with ID 0 is active by default; debug UI shows the current player ID via a dedicated 2D camera.

// --- Notes ---
// This application creates a 3D world with:
// - A static ground box and directional boxes (North, South, East, West) colored by world axes (Z, -Z, X, -X).
// - Players identified by `PlayerID`, each with a `Player` component and a `CameraPlayer` child (Camera3d).
// - Player 0 starts controllable with its camera active; Tab cycles through players.

# CMake configuration for SDL 3.2.4 project with additional libraries (shared libraries)
# This file sets up a project to build an SDL 3 application in C, fetching SDL and its
# extension libraries (SDL_ttf, SDL_image, SDL_mixer) directly from GitHub repositories.
cmake_minimum_required(VERSION 3.11)
# Notes:
# - CMake 3.11+ is required for FetchContent, which downloads and builds external dependencies.
# - We're using C (not C++) for main.c, which uses SDL 3's callback-based main functions.
