In the project settings, you can modify the environment. Choose the 
"run" configuration, and just add an environment variable. Name it 
whatever you want, like IN_QTCREATOR.

In your program, just use:

   qEnvironmentVariableIsSet("IN_QTCREATOR");

(http://doc.qt.io/qt-5/qtglobal.html#qEnvironmentVariableIsSet)

to detect if the variable is set. Obviously, it only going to be set if 
you run the program in Creator.
