1. Adapt to 4 inch screen adaptation.

For example, compiling matcaffe in Caffe requires GCC 4.7.X and later versions
Sometimes we encounter such a situation where a software is divided into several versions. In fact, most of the content is the same, but there are slight differences between several files. Therefore, we hope to compile different versions in the same project by setting certain conditions.
