Warning: Debugger speedups using cython not found

Whenever I start debugging, the following warning gets fired:

warning: Debugger speedups using cython not found. Run '"/usr/local/bin/python" "/opt/.pycharm_helpers/pydev/setup_cython.py" build_ext --inplace' to build.

I’ve found the issue to be addressed in

• https://blog.jetbrains.com/pycharm/2016/02/faster-debugger-in-pycharm-5-1,
• https://youtrack.jetbrains.com/issue/PY-18913,
• http://bryan7.tistory.com/838,

yet none worked out for me.

I’m well aware that it has nothing to with cookiecutter-django itself and rather the PyCharm version I’m using (EAP 2017.1), but I still hope I’m not the only one to stumble upon that and would appreciate any help.

@webyneter That message in the console is intended to provide a clickable link on some part of the text. Clicking it makes PyCharm go off and do everything it needs to do, for that version of Python.

The backstory: we ship the Cython binaries for Windows, but not for macOS nor Linux.

Running the command form the terminal (cmd in windows) gives a bit more insight about the error (at least in my case):

...
...\python_env\include\pyconfig.h(222): fatal error C1083: Cannot open include file: 'basetsd.h': No such file or directory

Based on this answer, adding the windows 8.1 / 10 SDK to the VisualC++ runtime installation fixed the problem.
