Running QT from the command line - qmake to run

[tbscope]

You're using a computer, so any automation goes, it only depends how.

To be more specific, what do you want to control?
You can add a lot of system checks in your .pro files.

By "launches QT" are we to assume that you mean "launch Qt Creator"? In that case, why do you need to involve Qt Creator at all? Simple Windows command file:

@echo OFF
CALL C:\Qt\2010.02.1\bin\qtenv.bat
CD /D D:\path\to\MyProject\
qmake
mingw32-make
COPY MyProject.DLL Q:\path\to\deployed\location\
 
REM commands to execute the deployed application or unit tests

@echo OFF
CALL C:\Qt\2010.02.1\bin\qtenv.bat
CD /D D:\path\to\MyProject\
qmake
mingw32-make
COPY MyProject.DLL Q:\path\to\deployed\location\

REM commands to execute the deployed application or unit tests

Path adjustments, error trapping etc. are left as an exercise.
