load_setup_py_data should cd to the directory containing setup.py

[jakirkham]

Actual Behavior

Currently load_setup_py_data does not appear to cd to where the setup.py file lives. This is a non-issue if the setup.py is in the top-level of the working directory as in PR ( conda-forge/metawrap-feedstock#9 ). However if the source directory is a subdirectory as in PR ( https://github.com/conda-forge/metawrap-feedstock/pull/10/files ), the lack of using cd results in files appearing as missing. The result is things like versioneer end up failing when a subdirectory is involved and load_setup_py_data is used.

Expected Behavior

It would be nice if we cded to the directory where the setup.py file lives before running it.

Steps to Reproduce

This recipe encounters the issue. Dropping the src folder "fixes" the issue.

# filename: recipe/meta.yaml

{% set name = "metawrap" %}
{% set data = load_setup_py_data(setup_file="src/setup.py") %}
{% set version = data.get("version") %}
