Summary0016006: Incorrect physical/logical core counts from kwsys on Windows
DescriptionI am not entirely sure if this is the right place for kwsys issues?

On a Windows 7 64-bit system with two of these:
http://ark.intel.com/products/47922/Intel-Xeon-Processor-X5650-12M-Cache-2_66-GHz-6_40-GTs-Intel-QPI [^]

Hyper-threading is enabled.

In cmsys::SystemInformation
  info.GetNumberOfLogicalCPU() returns 32 (expected is 24)
  info.GetNumberOfPhysicalCPU() returns 0 (expected is 2)

In CMake I exposed these values through
NUMBER_OF_LOGICAL_CORES and NUMBER_OF_PHYSICAL_CORES in
cmake_host_system_information().

The Windows GetSystemInfo() filled SYSTEM_INFO structure reports 24 in dwNumberOfProcessors.

Steps To Reproducecmake_host_system_information(RESULT PHYSICAL_CORES
    QUERY NUMBER_OF_PHYSICAL_CORES
)

cmake_host_system_information(RESULT LOGICAL_CORES
    QUERY NUMBER_OF_LOGICAL_CORES
)

message("[${PHYSICAL_CORES}:${LOGICAL_CORES}]")

KWSys does not have a separate issue tracker so this is fine.

For reference, KWSys Git repository instructions are here:
