This is because CMAKE_SIZEOF_VOID_P is undefined. Why it is undefined is yet to determine. One of the lead is that to determine this value, CMake has to dump data to a file, and so there might be something to do with permissions here, tough it's clearly not the obvious thing.
The problem has been reported on both Windows 7 and Linux but I can't reproduce it on any of my own machines, which make it even stranger.
