ValveSoftware/source-sdk-2013 ? reverse-engineered prompt

I'd like to get into modding for some classic Valve games like Half-Life 2 and Team Fortress 2. I found the official Source SDK 2013 source code on GitHub which seems to be the right starting point for making a mod.

Can you set up a project for me using that repository? The main goal is to get a development environment running on my Windows machine where I can successfully build the game code and eventually start making my own modifications. It should be configured so I can compile everything and then launch a basic test mod to see that it's all working. It looks like it requires Visual Studio and the Source SDK to be installed from Steam, so please make sure your setup process accounts for that.
