Hi John,

Ah, that was my second guess. My limited reading suggests that Windows
has completely separate compilers to produce x64 and x32
libraries/binaries. A bit of grubbing around the internet suggests
CMake exposes this with the CMAKE_GENERATOR_PLATFORM variable, and -A
on the command line. So I'd suggest:

-DLLVM_TARGETS_TO_BUILD=x86_64 -G "Visual Studio 14" -A Win64

(plus a path to the source). That last argument is a bit of a guess,
but fits in with documentation at
(for example).

Hope this works out for you.
