You are looking for "-D", warning it needs to be passed *before* -P

       -P <file>
              Process script mode.

              Process the given cmake file as a script written  in  the  CMake
              language.   No  configure  or generate step is performed and the
              cache is not modified. If variables are defined using  -D,  this
              must be done before the -P argument.
