%pyproject_buildrequires

  This will add build dependencies according to [PEP 517] and [PEP 518].

  If you need more dependencies, such as non-Python libraries, BuildRequire

  them manually.

  Adding run-time and test-time dependencies

  ------------------------------------------

  For this to work, the project's build system must support the

  [`prepare-metadata-for-build-wheel` hook](https://www.python.org/dev/peps/pep-0517/#prepare-metadata-for-build-wheel).

  The popular buildsystems (setuptools, flit, poetry) do support it.

  For projects that specify test requirements using an [`extra`

  provide](https://packaging.python.org/specifications/core-metadata/#provides-extra-multiple-use),

  these can be added using the `-x` flag.
