Extract new release of CMake for Linux

extactcmake.sh

tar xf ~/Downloads/cmake-3.11.1-Linux-x86_64.tar.gz -C ~/.local/ --strip-components=1
or
tar --extract --directory=$HOME/.local --file=$HOME/Downloads/cmake-3.11.1-Linux-x86_64.tar.gz --strip-components=1

I.e., tar-file content like this

    cmake-3.11.1-Linux-x86_64/share/cmake-3.11/completions/cpack
    cmake-3.11.1-Linux-x86_64/bin/ctest
    cmake-3.11.1-Linux-x86_64/bin/cmake
    cmake-3.11.1-Linux-x86_64/bin/cmake-gui
    cmake-3.11.1-Linux-x86_64/bin/cpack
    cmake-3.11.1-Linux-x86_64/bin/ccmake

will end up under

    ~/.local/share/cmake-3.11/completions/cpack
    ~/.local/bin/ctest
    ~/.local/bin/cmake
    ~/.local/bin/cmake-gui
    ~/.local/bin/cpack
