on windows 11 64bit: HWLOC target HWLOC::hwloc_1_11 doesn't exist.

### Checklist

- [x] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues).
- [x] For Python issues, I have tested with the [latest development wheel](https://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [x] I have checked the [release documentation](https://www.open3d.org/docs/release/) and the [latest documentation](https://www.open3d.org/docs/latest/) (for `main` branch).

### Steps to reproduce the issue

Hello, guys :)

I cloned actual project and did:

```
vcpkg install
```

`vcpkg list` gives me:

### Open3D, Python and System information

```markdown
- Operating system: Windows 11 64-bit
- System architecture: x86
- Is this a remote workstation?: no
- How did you install Open3D?: build from source
- Compiler version (if built from source): "Visual Studio 18 2026"
```

### Additional information

_No response_

Start with CMakeLists.txt and the CMake configuration command shown in the report, then inspect how the vcpkg-installed hwloc package is expected to define HWLOC::hwloc_1_11. Reproduce the x64 Windows configuration and consider the issue resolved when CMake completes without the missing-target error.
