'wheel' missing from setup.py install_requires list?

[miguelsousa]

While trying to use a vanilla cibuildwheel configuration with AppVeyor, I kept running into this error,

cibuildwheel: Failed to get name of the package. Command was ['c:\\python27\\python.exe', '.\\setup.py', '--name']

It was only after running that command (python .\\setup.py --name) ahead of the cibuildwheel --output-dir wheelhouse that I finally got a clue of what was going on,

setup requires that the Python package 'wheel' be installed. Try the command 'pip install wheel'.

To resolve this problem I've added 'wheel' to setup.py install_requires list in our fork.

I think that two changes are necessary:

1. On line 111 of __main__.py, print the output of CalledProcessError, and exit with the value of returncode.
2. Add 'wheel' to setup.py install_requires list

Do you want a PR?

Hey miguelsousa! Thanks for the debugging. Would love a PR for [1] above. Regarding [2], can you see where that error message is coming from? Perhaps there's something about your project's setup.py that requires it?

@joerick You were quite right about our setup.py; the wheel requirement came from it.
PR #88 is in.
