src/caffe/layers/window_data_layer.cpp:293:42: error: ‘CV_LOAD_IMAGE_COLOR’ was not declared in this

某次编译caffe时使用的是opencv4，编译过程中出现如下错误：

src/caffe/layers/window_data_layer.cpp:293:42: error: ‘CV_LOAD_IMAGE_COLOR’ was not declared in this scope
         cv_img = cv::imread(image.first, CV_LOAD_IMAGE_COLOR);

原因是在opencv4里面没有CV_LOAD_IMAGE_COLOR ，应该使用 cv::IMREAD_COLOR 来代替CV_LOAD_IMAGE_COLOR。

注意单词的拼写，后面的不是cv::IMAGED_COLOR，
