Struct Machine 

pub struct Machine {
    pub host: Option<Triple>,
    pub sysroot: Option<PathBuf>,
    pub sdk: Option<PathBuf>,
    pub include: Option<String>,
}

What the machine says about itself, and what the command line said over the top of it.

Separated from the lookup so that the lookup is a function of its arguments and can be tested for a platform the test is not running on. Everything here is read once, in system_dirs, which is the only place that talks to the environment.

Fields

host: Option<Triple>

The triple of the machine the compiler is running on, when it is one we know.

sysroot: Option<PathBuf>

--sysroot, which prefixes the configured directories, or -isysroot, which is the spelling Apple’s tools use and which means the same thing to us.

sdk: Option<PathBuf>

The SDK to compile against on an Apple platform, once it has been found.

include: Option<String>

The Windows SDK to compile against, as an INCLUDE spells one, once it has been found.

INCLUDE itself when the environment has it, which is what vcvarsall.bat sets and what every build on that platform already reads, and otherwise the same list assembled from the Visual Studio installation this machine has. The entries are separated by ;, which is a path separator there and a legal character in a file name nowhere.
