How to set different qmake configuration depending on debug / release?

Question

I need to specify different output and intermediate folders in my .pro file for debug and release builds. I created a following test .pro file:

release {
  messa

Try:

CONFIG(debug, debug|release){
message("debug")
} else {
message("release")
}

the qmake will display "debug" if you are building your project in a debug or debug|release mode, otherwise (i.e.: if you are building it in a release mode) a "release" message will be shown.
