# This script installs an up-to-date version of CMake.
#
# For MacOS use Homebrew to install the latest version.
#
# For Ubuntu use the official KitWare Apt repository with backports.
# See: https://apt.kitware.com/
#
# For other systems (RHEL 8.x, 9.x, AmazonLinux, SUSE, Fedora, Arch, etc)
# use the official CMake installer script from KitWare.
#
# Note this is similar to how GitHub Actions runners install cmake:
# https://github.com/actions/runner-images/blob/main/images/ubuntu/scripts/build/install-cmake.sh
#
# Upstream: 3.30.4 (2024-09-27)
