CMake

I am working on an HPC cluster with an outdated version of CMake. Can I still build waLBerla?

Yes; there are several ways to get an up-to-date version of CMake even without super-user rights on a machine.

Install CMake using pip (recommended)

If you have Python available, you may create and activate a new virtual environment and install CMake into it using pip:

pip install cmake

You can ensure that you are using the pip-installed CMake version like this:

which cmake  # should point to a path inside your virtual environment
cmake --version   # should be the latest CMake release

Download a Binary Distribution

You can download a binary distribution of CMake directly from cmake.org and install it into your user directory. In this case, you might have to manually add the installation directory to PATH.
