It should be possible to build using pyproject.toml (PEP517), Build-Depends: pybuild-plugin-pyproject The problem is that that method does not understand the --with-openmp flag added to setup.py in the same way as a distutils build (the flag is ignored) Discussed upstream at https://github.com/qutip/qutip/issues/1875 Upstream reports that the required flag with python3 -m build would be --config-setting="--global-option=--with-openmp" (and --build-option does not do the job). But --global-option gives an error for us (different python3-build versions?): File "/usr/lib/python3/dist-packages/setuptools/build_meta.py", line 211, in _build_with_temp_dir sys.argv = (sys.argv[:1] + setup_command + TypeError: can only concatenate list (not "str") to list Something else is needed.
