This script is used to update MSVC and Windows SDK environment variables on Windows systems, simplifying the C++ configuration of Visual Studio Code.

It performs the following tasks:

1. Check for Administrator Privileges: The script first checks if it is running with administrator privileges. If not, it prompts the user to run the script as an administrator and exits.

2. Get Latest Version Path: It scans the specified base paths to find the latest version of MSVC and Windows SDK installations.

3. Update Environment Variables:

/**
 * Convert standard camera intrinsic and extrinsic parameters to a vtkCamera instance for rendering
 * Assume square pixels and 0 skew (for now).
 *
 * focal_len : camera focal length (units pixels)
 * nx,ny : image dimensions in pixels
 * principal_pt: camera principal point,
 *    i.e. the intersection of the principal ray with the image plane (units pixels)
 * camera_rot, camera_trans : rotation, translation matrix mapping world points to camera coordinates
 * depth_min, depth_max : needed to set the clipping range

/*!
    This file contains code to convert unsigned integers to strings
    at compile-time, and then modify those strings include more
    information.
    
    One use case is to convert library MAJOR, MINOR, and PATCH
    numbers into a custom string (see below).
    
    Other types like signed integers and floats can be added
    with template specializition on the converter struct.

 * Features:
 *  - Mapping plain data types with no overhead (read/write access)
 *  - Mapping expressions via evaluation (read only acess)
