Are you running it with "cmake -P" ? If so, the variable CMAKE_SIZEOF_VOID_P is not defined, unless you define it yourself, and pass it in using -D when you call the -P script. It is only defined after enabling the C or CXX language (which is a side effect of the project command) during a CMake configure run. What does BuildSetup.cmake do?
