glslc Entry for Ubuntu Jammy

[meetgandhi-dev]

The glslc key was added as a part of PR #40284 .
The Ubuntu Jammy field is currently marked as null, but it is available through the vulkan-sdk. Do you think we can add an entry for it to resolve this issue?

@azeey I’m tagging you here for reference, in case you have any insights or suggestions regarding this.

@meetgandhi-dev There is no package called vulkan-sdk that's shipped with upstream Ubuntu Jammy (search), so I'm not sure how we can resolve this.

I also searched for packages that contain glslc (the binary file) in Jammy the results indicate that there's no such package.

It is coming from a third-party vendor.
I followed below steps to install the same:

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list https://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
sudo apt update

Here is the output dump:

Another point to note is that the repository does not support the arm64 architecture, so I'm unsure whether we can add the entry here.

N: Skipping acquire of configured file 'main/binary-arm64/Packages' as repository 'https://packages.lunarg.com/vulkan jammy InRelease' doesn't support architecture 'arm64'

I believe, as a policy, we can't use third-party vendors for rosdep, so I think we have to leave it unset for Jammy.

Okay. Thank you for the clarification.
