I think that the tutorial itself does not tell anything about the 
installation 
of the binaries, once built. Anyway, I was talking about the binary 
directory, 
that is the directory where the binaries are built. The installation 
directory 
(referred as CMAKE_INSTALL_PREFIX in CMake) is a different story.

Maybe the tutorial could document that installation part, the only one that 
may need the administrative privileges. But the installation on Windows, if 
CMake creates a Visual Studio solution, is done by Visual Studio itself, as a 
special target of the solution. I do not like the idea that Visual Studio is 
run with administrative privileges.

You are right that it would be a bad idea.
