@vasily-v-ryabov could you please confirm that there are enough changes for setup.
I saw that we use dev-requirements.txt in AppVeyor.yml and landscape.yml.
Shall I update them?

dev-requirements.txt contains all packages needed for development of pywinauto. This is not for end users. setup.py is for end user installation. There is new feature in pip to add sys.platform dependent packages into requirements file. Ideally we can modify dev-requirements.txt this way.
