Why does the compilation of opencv download lots of things?

I just downloaded the opencv 3.3.1 from the official website and compiled it successfully.

I've found that it downloaded many data files and put them into a hidden directory: .cache, whose size is 113 MB.

I think this directory is used to do some tests while compiling.

If I'm right, is it possible to pass over this download and these tests so that I can compile the whole opencv without Internet?

BTW, I have to choose 3.3.1 because my project depends on this version and I have no right to use another.

3.3.1 is outdated, why did you choose that ?
