CMake Configuration Step
Once paths.cmake is created, it’s time for CMake configuration step.
Create a build folder. I usually create two-level build paths: ./build/<build-specific-folder>, e.g. ./build/msvc10-amd64, ./build/make-x86, ./build/netbeans etc. But to keep things shorter, I will use ./build in the snippets below:
cd jancy_b
mkdir build
cd build
cmake ..
If all the required paths have been configured properly, you should see something like this.

Configuring done
After that you can optionally run:
cmake-gui .
This will launch a GUI client for CMake and allow you to fine-tune CMake configuration variables. For example, you may want to turn precompiled headers ON or OFF, change C++ RTTI settings, for make-based builds change configuration from Debug to Release or vice versa and so on.
You can also use cmake-gui all along for the whole CMake configuration process, without doing command line cmake step.
