Build failure on Jetson Thor (ARM64) – guidance on correct build steps + future support

### 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,

I’m trying to build Open3D from source on an **NVIDIA Jetson Thor (ARM64)** inside the official Isaac ROS container:

```
nvcr.io/nvidia/isaac/ros:noble-ros2_jazzy_d3e84470d576702a380478a513fb3fc6-arm64
```

My main requirements:

* **Offscreen rendering** (required)
* **GUI support** (optional)
* **CUDA support** (optional)

The build reproducibly fails around ~34% with a generic:

```
make: *** [Makefile:156: all] Error 2
```

No clear error message appears, even with Filament and OpenBLAS built from source.

**My questions:**

1. What is the **correct / recommended way to build Open3D** (with offscreen renderer, ideally with CUDA) on Jetson Thor?
2. Is **official Jetson Thor support** planned for future releases?
3. Will **ARM64 pip wheels** be provided for Thor / JetPack images?

Any guidance or known limitations would be greatly appreciated. Thanks!

CMake Deprecation Warning at CMakeLists.txt:200 (cmake_policy):
The OLD behavior for policy CMP0072 will be removed from a future version
of CMake.

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
