C code in Eclipse return undefined reference to symbol cvSaveImage

I'm using Eclipse and OpenCV (Version 3) on Ubuntu 15.10 to write a C program but I don't get why I'm always getting the error

undefined reference to symbol 'cvSaveImage'

If I run

pkg-config opencv --cflags --libs

I get

-I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib
-lopencv_shape -lopencv_stitching -lopencv_objdetect -lopencv_superres
-lopencv_videostab -lopencv_calib3d -lopencv_features2d 
-lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video 
-lopencv_photo -lopencv_ml -lopencv_imgproc -lopencv_flann 
-lopencv_core -lopencv_hal

So I added the LIbraries to the GCC C Liker as in the image below

enter image description here

If I don't try to use the function cvSaveImage the program runs, so the other libraries correctly work. I included the highgui library:

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include <stdbool.h>
#include <time.h>

Any idea?

cvSaveImage belongs to opencv_imgcodecs.

You are missing opencv_imgcodecs in the libraries (-l).
