CMake 2016
Introduction
CMake is an open-source, cross-platform family of tools designed to build, test and package software. CMake is used to control the software compilation process using simple platform and compiler independent configuration files, and generate native makefiles and workspaces that can be used in the compiler environment of your choice. The suite of CMake tools were created by Kitware in response to the need for a powerful, cross-platform build environment for open-source projects such as ITK and VTK. 1

Loading CMake
To load the desired version of the module, use the module load command, e.g.
module load hpc-env/8.3 module load CMake
Always remember: this commands are case sensitive!
Using CMake
The most common use case for using CMake is to configure a CMake-compatible software package from source and thereby creating a Makefile file to call make on. To do so, it is usually common to unpack the source file, cd into it, and create a folder called build. As a next step, cd into build and call
<cmake + options> ..
CMake will initialize and create temporary and log files within the current folder build. If CMake does not find any serious errors, it will create the Makefile in the current directory to which you now can call
<make + options>
To find out on how to use CMake you can just type in cmake --help after loading the module to print out a help text to get you started:
$ cmake --help
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
cmake [options] -S <path-to-source> -B <path-to-build>
Specify a source directory to (re-)generate a build system for it in the
current working directory. Specify an existing build directory to
re-generate its build system.
Options
-S <path-to-source> = Explicitly specify a source directory.
-B <path-to-build> = Explicitly specify a build directory.
-C <initial-cache> = Pre-load a script to populate the cache.
-D <var>[:<type>]=<value> = Create or update a cmake cache entry.
-U <globbing_expr> = Remove matching entries from CMake cache.
-G <generator-name> = Specify a build system generator.
-T <toolset-name> = Specify toolset name if supported by
generator.
