INCLUDEPATH in qmake project file doesn't work

Question

I\'ve got a problem with include in a qmake project. In my .pro file I\'ve got:

INCLUDEPATH += \"C:\\OpenCV\\build\\include\"

and in my cpp

Answer 1

here's one of my pro files:

    # Blah Application

TEMPLATE  = app
CONFIG   += qt console staticlib debug_and_release
QT       -= gui
QT       += network sql xml
TARGET    = blah

CONFIG(debug, debug|release){
    DESTDIR = debug
    LIBS += -L../../../lib/core/debug -lcore
} else {
    DESTDIR = release
    LIBS += -L../../../lib/core/release -lcore
}
DEPENDPATH  += . ../../lib ../../../lib/core
INCLUDEPATH += . ../../lib ../../../lib/core

# Library files
HEADERS += mtBlahRTP.h
SOURCES += mtBlahRTP.cpp

# Input
HEADERS +=
SOURCES += main.cpp

The include path points to the RELATIVE directory of my lib files. mtBlahRTP.h and mtBlahRTP.cpp are in ../../lib
