博客地址：https://www.cnblogs.com/zylyehuo/

卸载 cmake 4.1.2，安装 cmake 3.28.3

卸载已有的cmake

1. 查找CMake 4.1.2安装路径（通常是/usr/local/或~/cmake-4.1.2）

which cmake  # 输出路径如/usr/local/bin/cmake

2. 删除相关文件（替换路径为实际查到的）

sudo rm -rf /usr/local/bin/cmake

sudo rm -rf /usr/local/share/cmake-4.1.2

sudo rm -rf /usr/local/lib/cmake-4.1.2

3. 清理软链接

sudo update-alternatives --remove cmake /usr/local/bin/cmake

安装指定版本的cmake

wget https://github.com/Kitware/CMake/releases/download/v3.28.3/cmake-3.28.3.tar.gz

tar -zxvf cmake-3.28.3.tar.gz

cd cmake-3.28.3

./bootstrap

make -j4

sudo make install
