В виртуальной среде fre sh python3 .7 я пытаюсь установить загруженное колесо, но этап установки на Windows занимает ~ 20 секунд (на linux это немного быстрее, но все же ~ 20 секунд)
Выполненные шаги
Здесь я создаю venv, обновляю pip, setuptools & wheel, загружаю scons, здесь ничего особо интересного.

Могу ли я что-нибудь сделать, чтобы ускорить этап установки?
Обновление (13.07.2020):
После Комментарий bdbaddog Вскоре я взглянул на репо, поскольку он предположил, что в этой медленной установке виноваты артефакты dobook.
