[conda-forge-admin]

Hi! This is the friendly automated conda-forge-webservice.

I've started rerendering the recipe as instructed in #54.

If I find any needed changes to the recipe, I'll push them to this PR shortly. Thank you for waiting!

Here's a checklist to do before merging.

• [ ] Bump the build number if needed.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipe:

• This recipe is using a compiler, which now requires adding a build dependence on {{ stdlib("c") }} as well. Note that this rule applies to each output of the recipe using a compiler. For further details, please see https://github.com/conda-forge/conda-forge.github.io/issues/2102.

I'm hoping we can get this merged before the 28th. we are seeing a few environments of ours prioritize the newer zstandard which pulls in older versions of zstd which seems to conflict with newer versions of qt6.7.1
