declare libjpeg dep

[mfansler]

Adds explicitly libjpeg dependency. Since r-base=4.1 has not yet migrated, we split the declaration via variants.

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

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

For recipe:

• Failed to even lint the recipe, probably because of a conda-smithy bug 😢. This likely indicates a problem in your meta.yaml, though. To get a traceback to help figure out what's going on, install conda-smithy and run conda smithy recipe-lint . from the recipe directory.

@conda-forge-admin please rerender

The linter failure is expected, due to open bug: conda-forge/conda-smithy#1726.

Seeing clobber warnings both from this build (seems like vendoring deps) and from libjpeg-turbo + jpeg coinstallation.

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

I tried to rerender for you, but it looks like there was nothing to do.

This message was generated by GitHub actions workflow run https://github.com/conda-forge/r-cairo-feedstock/actions/runs/4612439208.

@hmaarrfk thanks for the quick reply! Where should I copy it to? I tried .ci_support/migrations/, but rerender bot found nothing to do. I expect it should update the pins in the .ci_support/*.yaml files.

Try: mfansler#1

lets see what happens in #20
