I just uing Ubuntu16.04. I have encountered an error as shown below.

CMake Error at CMakeLists.txt:5 (cmake_minimum_required):
  CMake 3.9 or higher is required.  You are running version 3.5.1


-- Configuring incomplete, errors occurred!
           

Let us solve this problem.

1. To install the latest version,we have first to remove the installed version.

sudo apt purge cmake
           

1. Then go to cmake and download the latest version you need.

• In my case cmake-3.12.1-Linux-x86_64.sh is sufficient.

1. chmod +x /path/to/cmake-3.12.1-Linux-x86_64.sh

   (use your own file location here, but chmod makes the script executable)

2. sudo ./path/to/cmake-3.12.1-Linux-x86_64.sh

   (you’ll need to press y twice)

3. sudo ln -s /path/to/cmake-3.6.2-Linux-x86_64/bin/* /usr/local/bin

   (Use absolute path.)
4. Test your results with

   cmake --version

   type

cmake -DCMAKE_BUILD_TYPE=Release .. && cmake --build .
           

Successful.
