How to edit Sublime Text build settings?

My original answer works, but there's a much better way of doing this, by creating your own build system. This use case is exactly why the feature is there.

Go to Tools → Build System → New Build System… (all the way at the bottom) and enter the contents below. Save as C++ 11 Single File.sublime-build, and it will now be accessible in the build system menu. Select it, hit CtrlB to build, and then hit CtrlShiftB to run the resulting program. Or you can use a Build and Run option and call it by hitting CtrlB, then selecting that option.

{
    "cmd": ["g++", "-std=gnu++11", "${file}", "-o", "${file_path}/${file_base_name}"],
    "file_regex": "^(..[^:]*):([0-9]+):?([0-9]+)?:? (.*)$",
    "working_dir": "${file_path}",
    "selector": "source.c, source.c++",

    "variants":
    [
        {
            "name": "Run",
            "cmd": ["${file_path}/${file_base_name}"]
        },
        {
            "name": "Build and Run",
            "cmd": ["g++ -std=gnu++11 ${file} -o ${file_path}/${file_base_name} && ${file_path}/${file_base_name}"],
            "shell": true
        }
    ]
}

If you need to edit it in the future, the file is in the User folder of Packages. The Packages directory is the one opened when selecting Preferences → Browse Packages…:

• Linux: ~/.config/sublime-text-3/Packages or ~/.config/sublime-text/Packages
• OS X: ~/Library/Application Support/Sublime Text 3/Packages or ~/Library/Application Support/Sublime Text/Packages
• Windows Regular Install: C:\Users\YourUserName\AppData\Roaming\Sublime Text 3\Packages or C:\Users\YourUserName\AppData\Roaming\Sublime Text\Packages
• Windows Portable Install: InstallationFolder\Sublime Text 3\Data\Packages InstallationFolder\Sublime Text\Data\Packages

^{The exact path depends on version and whether or not you upgraded from Sublime Text 3.}

In my case, the problem is that in Windows, ST3 was calling py instead of python which was the default. If you change python in "cmd": ["python", "-u", "$file"] for your local python interpreter, the new system should work.

{
        "cmd": ["python3", "-u", "$file"],
        "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
        "selector": "source.python",
    
        "env": {"PYTHONIOENCODING": "utf-8"},
    
        "windows": {
            "cmd": ["python", "-u", "$file"],
        },
    
        "variants":
        [
            {
                "name": "Syntax Check",
                "cmd": ["python3", "-m", "py_compile", "$file"],
    
                "windows": {
                    "cmd": ["py", "-m", "py_compile", "$file"],
                }
            }
        ]
    }
