Add a
pyproject.toml
file including the build system configuration as recommended by setuptools's docs.The current build process uses
setup.py install
which is deprecated in newer versions ofpip
. See the discussion in pypa/pip#8559 for more information. One of the recommended fixes to that is specifying the build system in apyproject.toml
file.I tested this by running
pip install .
with and without thepyproject.toml
configuration. By installing this project without the pyproject file, I was able to reproduce #42. By installing this project with the pyproject file, the warning vanished.Fixes #42.
