Add BUILD_DEBIAN_PACKAGE option for Debian package support

[meetgandhi-dev]

Introduced the BUILD_DEBIAN_PACKAGE CMake option to enable building a Debian package for the library. When this option is enabled and the host system supports Debian, the library will be packaged accordingly.

Usage:
To enable debian package building:
`cmake -DBUILD_DEBIAN_PACKAGE=ON <other_config_options> ..

To build debian package:
make package
or
cpack

Motivation and Context

This feature simplifies installation by allowing users to generate a Debian package directly through CMake, adhering to standard packaging conventions and enabling seamless integration with package management tools like apt. By streamlining the development workflow, we empower developers to focus on feature enhancement while encouraging community contributions and customisation. Overall, this initiative broadens our library's reach and strengthens its position within the open-source ecosystem, making it more user-friendly and accessible.

Hi @meetgandhi-dev This is a really useful PR. Can you add this to the CI, so we can test the resulting deb package?

You can add to the CI here. Essentially, just copy the steps we do for make package (tar.xz) (copying out of the docker container and uploading to github later, etc.). Let me know if you need help with this and I can help as well.

Hello @ssheorey
I have made the required changes as per my understanding. Let me know your feedback!

Hi @meetgandhi-dev can you check the CI? The deb package was not created (The CI runs on Ubuntu 20.04).

Hello @ssheorey ,
I’ve attempted to resolve the issue. Could you please check again with the latest version?

[ssheorey]

HI @meetgandhi-dev thanks for the update. I can now locally build the deb package and install it. One issue with the deb package is libtbb.so. Currently, we only package .tar.gz binary archives that are "all inclusive" and are locally installed. deb packages must however work with the OS, i.e. not conflict with other packages in the system. Currently, open3d will install libtbb.so, which conflicts with the system package libtbb. We need to make this change:

• Do not install libtbb for the deb package. It should still be included in the tar.xz package as before.
• Add a dependence for open3d on libtbb12, so that apt will install it for us.

[meetgandhi-dev]

@ssheorey Thanks for the heads up! When we disable the tbb build by setting -DUSE_SYSTEM_TBB=ON, it isn't being installed. Should we skip the installation even if USE_SYSTEM_TBB is set to OFF and TBB_BUILD is set to ON?

@ssheorey any updates here?

[ssheorey]

Yes, we should not install it in any case. Also, add it as a Debian package dependency, so that apt installs it from the Ubuntu repos.

[meetgandhi-dev]

@ssheorey
Thanks for the confirmation! I'm currently working on it. CMake can generate the dependencies on its own, and it's working on my machine, but not inside the Docker container. I'm investigating the issue and will update the PR with the requested changes soon.

[meetgandhi-dev]

@ssheorey It looks like this PR was closed while resolving the conflicts. I will reopen it once the issue is fixed.
