How to set compiler directives per build configuration

[GoDonkeys]

I have the following in my .pro file to send the -DDEBUG directive when I am using the debug configuration:
@CONFIG (debug)
{
DEFINES += DEBUG
}@

When I compile I get the following output, which I would expect

g++ -c -pipe -g -fPIC -Wall -W -D_REENTRANT -DDEBUG ...

The problem is that when I want to build a release version of my program, the -DDEBUG is still showing up when I compile even though it appears that the rest of the output is as I would expect

g++ -c -pipe -O2 -fPIC -Wall -W -D_REENTRANT -DDEBUG -DQT_NO_DEBUG -DQT_CORE_LIB -DQT_SHARED...

I'm using the DEBUG directive provide debugging output to the screen as well as intermediate files which will not be available for my release version.

Any help would be greatly appreciated.

I don something like this,

@

CONFIG(debug, debug|release) {
CONFIG_SUFFIX = Debug
DEFINES += _DEBUG
} else {
CONFIG_SUFFIX = Release
}

That did it.

Thanks!
