Qt Creator: add custom build configuration settings in .pro

Question

I am trying to add build settings for a custom build configuration.

By default Qt Creator creates debug and release configurations (http://doc.qt.digia.com/qtcreator-2.4/creator-build-settings.html).

For those configs you can add custom build settings. For ex:

release: DESTDIR = $${build_root_dir}/release
debug:   DESTDIR = $${build_root_dir}/debug

I created another build configuration called debug_menu_active in Qt Creator. And I'd like to use the same kind of statements:

debug_menu_active: DEFINES += FORCE_ACTIVE_MENU_DEBUG
debug_menu_active: DESTDIR = $${build_root_dir}/debug_menu_active

Unfortunately it doesn't work message("DEFINES: "$${DEFINES}) gives:

Project MESSAGE: DEFINES :UNICODE QT_LARGEFILE_SUPPORT

I think I need to define something else, but I have no clue what it could be.

Could someone help me with this?

Thanks!

Update:

I tested @svlasov answer, but unfortunately it breaks the compilation:

qtinternal\moc\moc_scenario.cpp:10:154: error: scenario.h: No such file or directory
qtinternal\moc\moc_scenario.cpp:12:2: error: #error "The header file 'scenario.h' doesn't include <QObject>."
qtinternal\moc\moc_scenario.cpp:20: error: expected constructor, destructor, or type conversion before 'static'
qtinternal\moc\moc_scenario.cpp:48: error: 'scenario' has not been declared
qtinternal\moc\moc_scenario.cpp:48: error: variable or field 'qt_static_metacall' declared void

qtinternal\moc\moc_scenario.cpp:48: error: '_o' was not declared in this scope

qtinternal\moc\moc_scenario.cpp:48: error: expected primary-expression before 'int'
qtinternal\moc\moc_scenario.cpp:48: error: expected primary-expression before 'void'

Here is how I did it:

Under Build Steps, for qmake step set Additional arguments as:

CONFIG+=debug_menu_active
