  rem Setup Environment Variables for Building
  rem =================================================================
  rem This script automatically configures the build environment by setting
  rem up the necessary environment variables for building the project.
  rem
  rem It dynamically detects and sets up:
  rem - Visual Studio installation path and version
  rem - Windows SDK location and version
  rem - VCPKG root directory
  rem - Include paths for headers
  rem - Library paths for linking
  rem - Binary paths for tools
  rem
  rem Features:
  rem - Automatic detection of latest Visual Studio installation
  rem - Dynamic Windows SDK version detection
  rem - Flexible VCPKG location discovery
  rem - Comprehensive error checking
  rem - Detailed progress reporting
