      Fixing "conversion from 'size_t' to 'uint', possible loss of data"
      warnings on Windows.

      Bug #13859866: VERSION_COMPILE_MACHINE SHOWS X86 FOR 
      64-BIT BINARIES ON 64-BIT WINDOWS MACHINE
      
      Added a workaround for a cmake deficiency that caused 
      the problem.
      Now the mysql cmake files will set the compile_machine
      to x86_64 when compiling a 64 bit windows binary.

    modified:
      CMakeLists.txt
      cmake/os/Windows.cmake
      config.h.cmake
