Detect version of MSVC in GYP

Question

I am trying to detect a version of msvc during node-gyp configurein my binding.gyp file. Basically, I want to be able to link to a specific 3rdparty library based on the Visual C ++ version:

['OS=="win"' and 'toolset="vc12"' , {
    'libraries': [
        "opencv/lib/vc12/opencv_world300.lib"
    ],
}],

['OS=="win"' and 'toolset="vc11"' , {
    'libraries': [
        "opencv/lib/vc11/opencv_world300.lib"
    ],
}],

['OS=="win"' and 'toolset="vc10"' , {
    'libraries': [
        "opencv/lib/vc10/opencv_world300.lib"
    ],
}]

Unfortunately, neither variables toolsetnor _toolsetnor are $(TOOLSET)they defined in GYP. I could not find such a variable in the GYP documentation. Is it possible at all?
