QT undefined reference to tesseract::TessBaseAPI::TessBaseAPI()

Code sample

#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>

#include <iostream>

using namespace std;

int main()
{
char *outText;

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();

}
getting error

C:\Users\66820\Documents\Tess\main.cpp:14: error: undefined reference to `tesseract::TessBaseAPI::TessBaseAPI()'

Pro File TEMPLATE = app

CONFIG += console

CONFIG -= app_bundle

CONFIG -= qt

SOURCES += main.cpp

LIBS +=-LC:\new\lib

-ltesseract3.02.02.dll

-llept.dll

-ltesseract

-lstdc++

INCLUDEPATH+=C:\new\include\

INCLUDEPATH+=C:\new\include\leptonica

INCLUDEPATH += C:\tesseract-ocr\api

changed pro.file to

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp

LIBS +=-LC:\new\lib
-ltesseract3.02.02.dll
-lllept.dll\

INCLUDEPATH+=C:\new\include
getting new errors:

:-1: error: cannot find -ltesseract3.02.02.dll
:-1: error: cannot find -lllept.dll

jsulm

LIBS +=-LC:\new\lib
-ltesseract3.02.02.dll
-lllept.dll\

Use forward slashes in paths:

LIBS +=-LC:/new/lib \
-ltesseract3.02.02.dll \
-lllept.dll

For linking on Windows you need *.lib files, not *.dll files (those are needed when executing the app).
It should look like this then:

LIBS += "C:/new/lib/tesseract3.02.02.lib" \
"C:/new/lib/llept.lib"
