https://docs.conda.io/projects/conda-build/en/stable/user-guide/tutorials/build-r-pkgs.html

And add it to jenkins release.

meta.yaml:

{% set major_version = '3.46.0' %}
{% set minor_version = '1' %}
{% set version = major_version + '.' + minor_version %}
{% set posix = 'm2-' if win else '' %}
{% set native = 'm2w64-' if win else '' %}
