sudo apt update
sudo apt install build-essential libtool autoconf unzip wget

# 1 -  Uninstall the default version provided by Ubuntu's package manager.
sudo apt remove --purge --auto-remove cmake
# or sudo apt purge --auto-remove cmake

# 2 - Go to the official CMake webpage, then download and extract the latest version.
#     Update the version and build variables in the following command to get the desired version:

version=3.16
build=3
## don't modify from here
mkdir ~/temp
cd ~/temp
wget https://cmake.org/files/v$version/cmake-$version.$build.tar.gz
tar -xzvf cmake-$version.$build.tar.gz
cd cmake-$version.$build/

# 3 - Install the extracted source by running:

./bootstrap
make -j$(nproc)
sudo make install
