Build Addon using VS2017

[eiximenis]

Just opening this issue for reference and keeping work on that :)

I've tried to build the project using gulp build --x64 with a Windows 10 having only VS2017 installed.
In the VS2017 installer the C++ workload ("Desktop Development with C++") was installed with both C++ toolsets: 141 (VS2017) and 140 (VS2015).

Using gulp build --x64 failed due to not founding msbuild. This can be solved by editing gulpfile.js and forcing toolsVersion to 15 in the msbuild call.
But node-gyp complains about compiling the addin node later.

Tried several things with no luck.

Finally I installed "Visual C++ Tools for VS2015" (http://landinghub.visualstudio.com/visual-cpp-build-tools) and reverting the toolsVersion to 14 in the gulpfile.js.
Some errors happening complaining about the file Microsoft.Cpp.Defaults.props. Finally need to set these two environment variables:

set VCTargetsPath=C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v140
set GYP_MSVS_VERSION=2015

This allowed the compilation of the project using Visual C++ 2015 Tools installed.

Real problem is node-gyp (gulp-msbuild works OK with VS2017): i could not make it work with having only VS2017 installed (even though i installed the 14.0 toolset).

I'll do some tests in the future and I'll update the status of this issue. :)
If anyone has any comment about building the project with VS2017 would be very appreciated.

Hi.

I was able to build with VS2017 by doing two things:

1. Installing the VS2015 cpp tools (http://landinghub.visualstudio.com/visual-cpp-build-tools)
2. Then setting some environment variables:

set VCTargetsPath=C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v140
set GYP_MSVS_VERSION=2015

This is the best way I found :)
