+Path to standalone NVIDIA CUDA Toolkit (eg. extracted from installer).
+
+The :ref:`Visual Studio Generators` for VS 2010 and above support using
+a standalone (non-installed) NVIDIA CUDA toolkit.  The path
+may be specified by a field in :variable:`CMAKE_GENERATOR_TOOLSET` of
+the form ``cuda=C:\path\to\cuda``.  The given directory must at least
+contain a folder ``.\nvcc`` and must provide Visual Studio integration
+files in path ``.\CUDAVisualStudioIntegration\extras\
+visual_studio_integration\MSBuildExtensions\``. One can create a standalone
+CUDA toolkit directory by either opening a installer with 7zip or
+copying the files that are extracted by the running installer.
+The value may be empty if no path to a standalone CUDA Toolkit was
+specified.
