как пример, мой порядок в проекте:
C++ (Qt)
TEMPLATE = app
DESTDIR = ../bin
UI_DIR = build
RCC_DIR = build
CONFIG(debug, debug|release) {
TARGET = tabletGUI_d
CONFIG += console
OBJECTS_DIR = build/debug
MOC_DIR = build/debug
}
else {
TARGET = tabletGUI
CONFIG += console
OBJECTS_DIR = build/release
MOC_DIR = build/release
}
