`build` seems to rely by default in the stdlib's implementation of `venv` and unfortunately for a specific combination of Windows + conda env + virtualenv (as used by tox), that might be problematic as identified in pyscaffold/pyscaffoldext-markdown#10. According to the discussion in pypa/build#253, specifying `virtualenv` as an extra dependency of `build` seems to be a good workaround. Moreover I would expect some kind speed improvements (virtualenv is reported to be faster than venv).
