Variable is now a subclass of at::Tensor backed by a VariableImpl* pImpl. The implementation of the ATen functions is defined in the auto-generated VariableType.h/cpp file.
Currently, only functions which fall through to the base type, such as sizes() and isCuda() are implemented. Differentiable ops like add() and mul() will be added in a subsequent PR.
Summary:
I successfully built caffe2 using MSVC 2015 and the Ninja Generator. I use vcpkg to build glfags, glog, lmdb and protobuf. Here is my build procedure:
1. Install vcpkg and set it up according to vcpkg docs
2. Install dependencies
```
$> vcpkg install gflags glog lmdb protobuf eigen3 --triplet x64-windows-static
```
3. Run CMake with this batch file
```Batch
setlocal
if NOT DEFINED VCPKG_DIR ( echo "Please defined VCPKG_DIR" && exit /b 1 )
if NOT DEFINED CMAKE_BUILD_TYPE set CMAKE_BUILD_TYPE=Release
if NOT DEFINED BUILD_DIR set BUILD_DIR=build_%CMAKE_BUILD_TYPE%
if NOT DEFINED USE_CUDA set USE_CUDA=OFF
call "%VS140COMNTOOLS%\..\..\VC\vcvarsall.bat" amd64
if NOT EXIST %BUILD_DIR% (mkdir %BUILD_DIR%)
pushd %BUILD_DIR%
set CMAKE_GENERATOR=Ninja
set ZLIB_LIBRARY=%VCPKG_DIR%\installed\x64-windows-static\lib\zlib.lib

Summary:
Fixed a bug in CMakeLists.txt: should not use option cmd for setting the initial value(empty string) of CAFFE2_CPU_FLAGS and CAFFE2_WHITELIST, because option can only be used for boolean(ON/OFF) variables. Use set cmd instead. The bug can cause compilation errors if CAFFE_CPU_FLAGS is set to ON, since an invalid 'ON' flag will be added to CXX_FLAGS. (2) Add build_* in .gitignore to allow multiple build directories in repo
