Compilation error on Ubuntu 22

[t-fi]

Checklist

• I have searched for similar issues.
• For Python issues, I have tested with the latest development wheel.
• I have checked the release documentation and the latest documentation (for master branch).

Steps to reproduce the issue

I followed the official instructions form here:
http://www.open3d.org/docs/latest/compilation.html#compilation

With the addition of git checkout v0.17.0 after cloning. [I also just tried v0.16.1, same error :( ]

cmake configuration and downloading/building dependencies seems to work fine. However Open3D compilation fails at ~50% with the following error.

Open3D, Python and System information

- Operating system: Ubuntu 22.10
- Python version: Does not apply
- Open3D version: 0.17.0
- System architecture: x86
- Is this a remote workstation?: no
- How did you install Open3D?:  build from source
- Compiler version (if built from source): Here's the cmake output:

-- CMAKE_BUILD_TYPE is set to Release.

CMake Deprecation Warning at CMakeLists.txt:189 (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.

This is a legitimate coding issue, the errors (may have been a warning before) point to logical errors in the programming.

I've come across this while trying to build and had to manually resolve the logical issues with this code as best as I could, but this code base (and some of its dependencies) seriously needs to be looked at to do some quality control.

The compilation/build process for this library is overall horrendous, more so than other large libraries of comparable or greater complexity (for example OpenCV.)
