CMakeLists.txt

# Installing correct cmake version is easy!
# 1) Find the respective version here;
# https://github.com/Kitware/CMake/releases,
# and 2) replace the [x.xx.x] in the following
# commands with the version number (remove the
# brackets). For example, if you are installing
# CMake 3.22.1, replace [x.xx.x] with 3.22.1:

# wget https://github.com/Kitware/CMake/releases/download/v[x.xx.x]/cmake-[x.xx.x]-linux-x86_64.sh
# chmod +x ./cmake-[x.xx.x]-linux-x86_64.sh
# ./cmake-[x.xx.x]-linux-x86_64.sh
# sudo mv cmake-[x.xx.x]-linux-x86_64 /opt/cmake
# sudo ln -s /opt/cmake/bin/* /usr/local/bin/
