Installation error

I am getting this error while using cmake …/root-6.16.00

CMake Error: CMake was unable to find a build program corresponding to “Ninja”. CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
– Configuring incomplete, errors occurred!

I think the error is telling you not to use -GNinja but just leav this switch aside since you do not have ninja installed.
