1. 删除旧版本的 cmake

apt remove --purge --auto-remove cmake
apt purge --auto-remove cmake

2. 安装包源

apt update && apt install -y software-properties-common lsb-release
wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null
apt-add-repository "deb https://apt.kitware.com/ubuntu/ $(lsb_release -cs) main"

可选操作

apt update
apt install kitware-archive-keyring
rm /etc/apt/trusted.gpg.d/kitware.gpg

如果执行 apt update 报错，并且错误中有 the public key is not available: NO_PUBKEY 6AF7F09730B3F0A4 ，则执行如下操作把这个 key 添加到系统里面

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6AF7F09730B3F0A4

3. 安装最新版 cmake

可以先使用 apt search cmake 查看默认 cmake 包的版本，然后执行下面的命令进行安装

apt update
apt install cmake

4. 安装编译工具

apt install build-essential libtool autoconf unzip wget
