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.
- To install the latest version,we have first to remove the installed version.
sudo apt purge cmake
- Then go to cmake and download the latest version you need.
- In my case cmake-3.12.1-Linux-x86_64.sh is sufficient.
chmod +x /path/to/cmake-3.12.1-Linux-x86_64.sh(use your own file location here, but chmod makes the script executable)sudo ./path/to/cmake-3.12.1-Linux-x86_64.sh(you’ll need to press y twice)sudo ln -s /path/to/cmake-3.6.2-Linux-x86_64/bin/* /usr/local/bin(Use absolute path.)- Test your results with
cmake --version
type
cmake -DCMAKE_BUILD_TYPE=Release .. && cmake --build .
Successful.
