Qt Creator can't even build default new project successfully.

[MXXIV]

I'm not actually convinced this is the right way to make android apps, but I can't chose my tools so I am making C++ Qt Android app.

I downlaoded this software:

• Android SDK
• Android SDK
• Qt libraries for android (windows-x86-android-5.5.1.exe)
• Qt Creator

This is all based on this tutorial: http://doc.qt.io/qt-5/androidgs.html
I started Qt Creator and created C++ empty project expecting everything is going to work. But it doesn't even compile:

The full output:

Solved, cygwin was missing in the system.
