Summary:
aaronmarkham this solves your Windows build issue. Basically:
(1) VS 2017 does not have CUDA support yet, and we will be waiting on NVidia to do so.
(2) VS 2015 and 2017 need different cmake generator strings.
This PR shows how to determine those and also updates appveyor to do contbuild guard for the following 3 settings:
- VS2015 without cuda
- VS2017 without cuda
- VS2015 with cuda

Summary:
(Note: previous revert was due to a race condition between D4657831 and
D4659953 that I failed to catch.)
After this, we should have contbuild guarding the Windows build both with
and without CUDA.
This includes a series of changes that are needed to make Windows build,
specifically:
(1) Various flags that are needed in the cmake system, specially dealing
with /MD, /MT, cuda, cudnn, whole static linking, etc.
(2) Contbuild scripts based on appveyo.
(3) For Windows build, note that one will need to use "cmake --build" to
build stuff so that the build type is consistent between configuration and
actual build. see scripts\build_windows.bat for details.
(4) In logging.h, ERROR is already defined by Windows. I don't have a good
solution now, and as a result, LOG(ERROR) on windows is going to be
LOG(INFO).
(5) variable length array is not supported by MSVC (and it is not part of
C++ standard). As a result I replaced them with vectors.
(6) sched.h is not available on Windows, so akyrola 's awesome simple
async net might encounter some slowdown due to no affinity setting on
Windows.
(7) MSVC has a bug that does not work very well with template calls inide
a templated function call, which is a known issue that should be fixed in
MSVC 2017. However for now this means changes to conv_op_impl.h and
recurrent_net_op.h. No actual functionalities are changed.
(8) std host function calls are not supported in CUDA8+MSVC, so I changed
lp_pool (and maybe a few others) to use cuda device functions.
(9) The current Scale and Axpy has heavy templating that does not work
well with MSVC. As a result I reverted azzolini 's changes to the Scale
and Axpy interface, moved the fixed-length version to ScaleFixedSize and
AxpyFixedSize.
(10) CUDA + MSVC does not deal with Eigen well, so I guarded all Eigen
parts to only the non-CUDA part.
(11) In conclusion, it is fun but painful to deal with visual c++.
