[CMake] CMAKE_SIZEOF_VOID_P empty when bootstrapping ?

[Alexander Neundorf]

Hi,

I'm currently trying to build cmake on Syllable (www.syllable.org), which is 
mostly POSIX compliant, and there are indeed not many problems.

One issue I have is that after creating the bootstrap-cmake 
CMAKE_SIZEOF_VOID_P is empty (i.e. in CMakeFiles/CMakeCCompiler.cmake) and 
doesn't appear at all in the CMakeCache.txt.

Usually this is set by CMakeTestCCompiler.cmake, is this also the case when 
bootstrapping (I think there is no cmake yet which could execute that file) ?
