Heya,

QtWebEngine under Windows requires Visual Studio unfortunately, MinGW is not 
supported, see:
  https://bugreports.qt.io/browse/QTBUG-42725

Cross-compiling KDevelop from FreeBSD/Linux was never attempted and personally 
I would not go down this rabbit hole in case you feel familiar on Windows 
anyway, and would like to /work/ on Windows using KDevelop.

For non-enterprise use cases you could just use MSVC Community edition, which 
is free of charge.

Alternatively, you can try what RJVB suggested: Try building KDevelop against 
QtWebKit using the CMake arguments RJVB provided; but doing so using KDE Craft 
requires changing the Craft recipes (more involved). You'll need to add the 
QtWebKit dep and then also disable finding QtWebEngine. For instance, look at 
kate.py inside craft-kde-blueprints.git:

```
kde/applications/kate/kate.py
51:            self.subinfo.options.configure.args += " -
DCMAKE_DISABLE_FIND_PACKAGE_KF5Plasma=ON"
```

All untested terrain though.

Hope that helps,
Kevin
