Cannot generate 64 bit configuration for Visual Studio 2017 with host=x64

CMake version: 3.10.0-rc3

Even though I specify 'host=x64' at the time of creating the configuration, I can see CMake use cl.exe from:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.11.25503\bin\Hostx64\x86

However, Visual studio 2017 has another cl.exe in:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.11.25503\bin\Hostx64\x64

When the configuration is generated, there is still only the Win32 option where the target in the linker options is still /MACHINE:X86.

What makes things worse, is that even when using Visual Studio to create a new x64 configuration from the Win32, there are still problems because CMake injects a hard-coded "%(AdditionalOptions) /machine:X86" for the "Additional Options" in the linker, thus causing the builds to fails for every project (in a complex system this can be in the hundreds of sub-projects) with the errors of conflicts specifying both x86 and x64 targets.

I do not know if this was an issue in VS 2015 as I no longer use that. I also do not know if this is an issue in the community version.
