Distribute source code with .tar.xz archives instead of .tar.gz
Currently CMake source code is distributed using .tar.gz archives. In my opinion Cmake should use .tar.xz archives instead.
On my system:
$ du -k cmake-3.12.1.tar.??
7904 cmake-3.12.1.tar.gz
5524 cmake-3.12.1.tar.xz
By using the XZ format we can save about 30% of disk space and bandwidth.
What do you think?
