[Interest] qt.conf

[Hugo Drumond Jacob]

Hello Graham!

On Windows, you can add the Qt library path (directory with .DLL files) to
the environment path (PATH environment variable).

The qt.conf file is used only after your application starts. Before this,
Windows need to know all .DLL files used by your program (like ldconfig on
Linux).

If you don't know how try this, see
http://www.computerhope.com/issues/ch000549.htm to reference.
