When it comes to integrating third-party libraries in C++, things can get a bit messy. But fear not, my friends! We have a lifeline called VC Package, which makes this process a whole lot smoother. So, let’s dive in and explore the wonders of VC Package and how it can simplify your life.

Setting Up VC Package
First things first, we need to make sure VC Package is up and running. To get started, you can clone the repository and run the “bootstrap” command. But here’s the good news: if you have the latest version of Visual Studio, you probably already have VC Package installed. All you need to do is find it and run the “VC Package Integrate Install” command to link it up.
Two Ways to Use VC Package
Now that we have VC Package set up, let’s explore the two ways to use it. The first way is to make the packages globally available on your system. This means that any project you build on this system will be able to link to those packages and find the headers without any hassle.
The second, and better, way is to use a VC Package Manifest. By creating a VC Package JSON file, also known as a manifest, you can specify the third-party dependencies your project requires. When someone pulls your project from GitHub, for example, they won’t have to figure out which packages they need to install. The manifest will automatically install the necessary dependencies during the build process.
Creating a VC Package Manifest
To create a manifest, simply create a new file called “vcpkg.json” (or any name you like) and specify the dependencies you need. This JSON file acts as a central hub for your entire solution, making it easy to manage. Plus, it even provides auto-completion and intellisense support to help you along the way.
Simplifying Setup with Property Sheets
Now, here’s where it gets a little tricky. By default, projects use VC Package but don’t use the manifest. But fear not, here’s a workaround. You can create a property sheet to manage the VC Package settings in a central place. Although there’s no UI support for this in the property sheet editor, you can easily add these settings manually. Simply create a property sheet file and add the necessary VC Package settings. Then, add this property sheet to your project, and voila! You have a centralized way to manage VC Package settings for all your projects.
Unleashing the Power of CLI11 Library
Now that we have VC Package set up and our manifest in place, let’s explore the CLI11 library. CLI11 is a remarkable command line parser that simplifies the process of parsing and handling command line arguments.
With CLI11, you can create an app object and add options to it. These options can be bound to data in your program, making it easy to process command line arguments. CLI11 also provides automatic validation and error handling, ensuring that your program receives valid input. Plus, it even generates a help page for your program, making it easy for users to understand the available options.
A Sneak Peek at CLI11 in Action
To give you a taste of what CLI11 can do, let’s create a simple example. We’ll define an options struct to hold our options, bind them to switches on the command line using the CLI11 API, and then parse and output the results. With CLI11, you can easily define options and their descriptions, automatically validate input, and generate help pages. It’s truly a powerful tool for handling command line arguments.
Wrapping Up
And there you have it! We’ve explored the power of VC Package and how it simplifies third-party library integration in C++. We’ve also discovered CLI11, a fantastic command line parser that makes handling command line arguments a breeze.
Next time, we’ll dive deeper into the amazing features of CLI11 and explore its full potential. So stay tuned and happy coding!
