Автоматические #defines в соответствии с конфигурацией Debug / Release в Visual Studio

I have debug output in my program like this:

#define DEBUG
...
#ifdef DEBUG
    std::cout << "[RE_words] " << m_re << std::endl;
#endif

and DEBUG is defined in my program manually. I always comment out the line when I make a release version. In Visual Studio, there are also Configurations for Debug vs Release versions which handle the commandline etc. used for compiling. Can I also use the Configuration "Debug" to automatically define DEBUG to the compiler? How?
