-Open CMake, select the ktools directory as the source folder ("Where is the source code") and whichever directory you'd like as the build folder ("Where to build the binaries"). Click "Configure" and select a generator (typically either a version of Visual Studio of "MinGW Makefiles"). Leave "Use default native compilers" checked and click "Finish". If you with to customize some compilation option (which shouldn't be necessary) do so now, in the options presented in red after the configure step finishes. If any option was changed, click "Configure" again. Finally, click "Generate", which should place the project files in the build directory you selected.
