cmake reported an error:
CMake 3.8 or higher is required. You are running version 3.5.1
It indicates that the current version of cmake is too low.
1. View the current cmake version:
2. Uninstall the current cmake: (skip this step if ROS is installed)
sudo apt remove cmake
3. Download cmake:
Directly from cmake official website To download the new version, you can also execute the following statement:
I download cmake-3.16.6 here.
Or go to the file library to download: https://cmake.org/files/v3.16/
Note: there are two versions on the official website, one is the Source version, and the other is Linux x86 ʄ in Binary distributions. This is a compiled executable version that can be used directly. You only need to establish a soft connection, and call cmake GUI to use cmake by establishing a soft link.
What I download here is the source version ending with. tar.gz.
4. Decompression and installation:
tar xf cmake-3.16.6.tar.gz #Unzip, or right-click to extract it directly cd cmake-3.16.6
sudo apt-get install build-essential
Go to the folder, if there is a lock indicating that there is permission setting, return to the upper directory of cmake-3.16.6, and modify the file permission
sudo chmod -R 777 cmake-3.16.6
If there is an error in this step, please refer to the following solutions for errors.

Error 3: when executing cmake --version, it indicates that there is no file or directory:
bash: /usr/bin/cmake: no file or directory
Use which cmake to find the installation path of cmake, which is in / usr/local/bin/cmake by default, and the system will search in / usr/bin by default.
Make a link:
ln -s /usr/local/bin/cmake /usr/bin
Add sudo if you don't have permission.
