Add preprocessor definition only for Release build in Qt Creator

Asked 2012-11-24T07:27:47.863

I want to define QT_NO_DEBUG_OUTPUT for Release build, but I couldn't find where to add it.

I need the preprocessor definition to be Release-specific, i.e. it should affect the Release build, but not the Debug build.

I'm looking for the equivalent of this (it's in Visual Studio):

In your project file:

CONFIG(release, debug|release) {
    #This is a release build
    DEFINES += QT_NO_DEBUG_OUTPUT
} else {
    #This is a debug build
}

Note that CONFIG can contain both "release" as well as "debug". Only the last is effective, which is what the above check does. This is explained here:
