c_stdlib_version in conda_build_config.yaml ignored when cuda is used #1950

Solution to issue cannot be found in the documentation.

Issue

Packages that optionally use cuda compilers and specify c_stdlib_version: 2.17 # [linux] in conda_build_config.yaml are still getting builds for cuda_compiler=None, c_stdlib_version=2.12. I'm guessing this relates to the complex zip_keys for cuda and c_stdlib_version not handling conda_build_config at highest priority. I'm not 100% certain it's cuda related, but I've seen it twice (openmpi and lammps), both of which use the cuda compilers and have no-cuda variants which still want to use 2.17.

This can be worked around in this specific case by specifying os_version: cos7 in conda-forge.yml, but presumably something is wrong in the rendering.

example: https://github.com/conda-forge/lammps-feedstock/pull/198 which migrates from sysroot_linux-64 2.17 to c_stdlib_version pinning, which has no effect.
