Static builds of QtWebEngine aren't supported

New code using QtWebEngine throw me the next error when compiling:

```
Static builds of QtWebEngine aren't supported.
QtWebEngine will not be built.
make: No se hace nada para 'first'.
Info: creating stash file /home/piranna/github/noGUI/build/nogui/.qmake.stash
Project ERROR: Unknown module(s) in QT: webenginewidgets
```

We'll need to find a solution for this...
