[Qt-creator] CMake configuration loop when using vcpkg

[Cristian Adam]

Hi Jakub,

The infinite CMake loop bug is still not yet fixed.

See https://bugreports.qt.io/browse/QTCREATORBUG-25346 for a similar 
vpkg report.

The workaround that seems to work is unchecking "Autorun CMake" in Qt 
Creator settings.

Cheers,
Cristian.
