CMake is an open-source, cross-platform family of tools designed to build, test and package software.
All managed Linux workstations and clusters
A version of cmake is automatically available on the PATH. There may also be environment modules available to load other versions depending on which version of the Linux workstation image you're using. To load an environment module
module add cmake
Cmake is open source, using the BSD 3-clause licence. See https://cmake.org/licensing/ for details.
There are manpages.
For alternative versions on the workstations I've used the binary distribution from cmake.org. For the clusters there's an RPM specfile in the specfiles repository which can be used to build newer versions.
