If I install python3 bindings from the standard apt repository, it works! By default, this version just find 'libclang-10.so'. But if I use 'pip3' to install python3 bindings, it doesn't work. Because it is another verison. This version find 'libclang.so' and it can't find it! So I think we can retain these lines to adapt to the distinction among platforms.
