The possible reason for opencv cannot find .png format images - opencv

Question

I just find my opencv cannot find .png format images, but works fine with loading other format like .jpg images. I built opencv4.01 with vs2015. Here below are the CMake configurations I saved when the opencv was built:

I wonder if there are any modules I missed for loading .png images, or other reasons for that failure.
