CMake Error at CMakeLists.txt:3 (cmake_minimum_required):
CMake 3.4.3 or higher is required. You are running version 2.8.12.2
while installing last version of ROOT (Release 6.10/06 - 2017-09-19). I have installed cmake3, however, it does not help to get rid of the error. Please advice.
Are you sure cmake version 3 is installed correctly? What does cmake --version print? Do you have multiple cmakes installed? Then you might need to specify the full path to the βnewβ cmake.
