 We are using cmake to create build / IDE projects in a platform independent manner. You will need an installation of CMake to use our project. CMake exists for many platforms and HPC systems usually have some version installed.
 
+**Gui**

 If you are working on a PC, then you can use the cmake-gui, where you can choose the generator (like Visual Studio projects or Unix Makefiles) with the compiler and then configure the build project.
 
-If you are using Visual Studio you can alternatively import source code directly as CMake project, which will create a new `out/` subfolder and uses the ninja build system in the back.

-If you only have a terminal (for example on a remote cluster), then you can use the the gui-like terminal program ccmake or directly cmake.
