[Qt-creator] Unable to configure plain C++ project in Qt Creator without Qt installed

[Orgad Shaneh]

IIRC, what you need is:
bin/qmake.exe
bin/QtCore4.dll
mkspecs/*
include (can be empty, but should exist)

The absolute paths must be identical on all machines. Install Qt on one
machine then use the same path on all others.
