 * python3_9: running distutils-r1_run_phase distutils-r1_python_compile
python3.9 setup.py build -j 4
error: Multiple top-level packages discovered in a flat-layout: ['cmake', 'symengine'].

To avoid accidental inclusion of unwanted files or directories,
setuptools will not proceed with this build.

If you are trying to create a single distribution with multiple packages
on purpose, you should not rely on automatic discovery.
Instead, consider the following options:

1. set up custom discovery (`find` directive with `include` or `exclude`)
2. use a `src-layout`
3. explicitly set `py_modules` or `packages` with a list of names

To find more information, look for "package discovery" on setuptools docs.
