How to use debug/release switch in *.pro?

fasix

I have installed qt-4.8.6,worked with qt-creator2.7.0.

I created a project, and I want to make it different between debug and release, such as:

debug{

config += APP_OUTPUT_DEBUG_LOG_ON

}else{

config+=APP_OUTPUT_DEBUG_LOG_OFF

}

but It seems no effect, Because it always performed the first swtich:
------ APP_OUTPUT_DEBUG_LOG_OFF.

when i output the config value:
message(config)

It always contains both debug and release, perhaps this is the original reason.

How can I fix this?

try
CONFIG(debug, debug|release) {
#debug settings here....
}else{
#release settings here....
}
