At llvm HEAD from this morning (69090143f5022da526c0a3b81ced530fce832769) in a Visual Studio 2019 x86 development shell:
(The same commands fail in an x64 shell, but in slightly different ways.)
Configuring:
```

```
Let's test it:

```
(That looks like it's baked three command-line arguments into one which seems like a bug.)
```

That's not good.
Maybe it's a missing build dependency. Let's try building "all" before running the tests.
