No one has to set a magic variable in Alex's current design either.
The CMAKE_PROJECT_VERSION_SET_BY_PROJECT_COMMAND variable is set
and unset by the project() command automatically.  One need only to
set it when one wants to manually set PROJECT_VERSION after using
project(VERSION) in new code.  That seems unusual.
