Geant4 installation process error

Hi geant4 familly!
I’m a geant4 beginner, I try to install geant4, but I got the message error below. Can someone help me to fix it ?

You should substitute /path/to with some real path (it is used for illustration only in the installation guide):
cmake -DCMAKE_INSTALL_PREFIX=/path/to/geant4.10.06-install [...]

Thank’s Anna ! the problem it’s solved, I finished the installation without error.
