See 2 example picture with the White/Blue pattern. I tried the square.cpp from the library and it didn't detect any of the squares in the pictures. Is there any need to adjust one of the parameters?
Squares.cpp looks for angles that are approximately 90 degrees between two edges of a given contour. Since you have perspective and camera deformations, it will possible find the contours, but the relations in order to have a square (90° angles and same size borders) form will not get satisfied.
What you could do is define a relation of your own, which could help you detect all objects with 4 linear sides or you could perform segmentation based on color thresholding.
