Summary0014342: CMAKE_SYSTEM_PROCESSOR behaviour changed
DescriptionThe behaviour of the value of CMAKE_SYSTEM_PROCESSOR appears to have changed somewhere between 2.8.10.1 and 2.8.11.2. I build 32-bit apps on a 64-bit Windows 7 system and I use VS2008 (express version, no 64-bit compiler). With CMake 2.8.10.1, CMAKE_SYSTEM_PROCESSOR is reported to have the value x86, but with 2.8.11.2, now it has the value AMD64. I verified this with both versions of CMake and testing a trivial CMake project that simply prints the value of the variable.

According to the CMake documentation, on the one hand, the value should have always been AMD64 since the documentation says it just pulls the value from the PROCESSOR_ARCHITECTURE environment variable. On the other hand, this conflicts with the statement that it should reflect the target architecture. I think x86 would be the correct value here rather than simply reporting whatever PROCESSOR_ARCHITECTURE says, since that environment variable is not going to always match the target architecture.

 FYI, I'm using the NMake Makefiles generator with cmake/cmake-gui launched from the VS2008 command prompt shell.

 Just out of curiosity: have you build the CMake version yourself and have build a 64 bit one?

 Nope, I'm using the 32-bit pre-built binaries from Kitware's download area.
