In the qmake manual it says to make a file named "hello.pro" with the following lines:

CONFIG += qt
HEADERS += hello.h
SOURCES += hello.cpp
SOURCES += main.cpp

You can now use qmake to generate a Makefile for your application. On the command line, in your project's directory, type the following:
qmake -o Makefile hello.pro


Here's my question:

qmake.exe and the project's directory are generally not in the same place, so if I type "qmake" in the project's directory it says "qmake is not a recognized command".
I don't know very much about the DOS command line. How can I make this work?

What is "computer property -> advance" and how do I get to it?
I am in Windows Vista.

never mind...
The keyword "set path" in your reply was enough for me to look it up.

Thanks!
