# CMAKE_VS_PLATFORM_TOOLSET_CUDA_CUSTOM_DIR

Added in version 3.16.

Path to standalone NVIDIA CUDA Toolkit (eg. extracted from installer).

The 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 `CMAKE_GENERATOR_TOOLSET` of the form `cuda=C:\path\to\cuda`. The given directory must at least contain the nvcc compiler in path `.\bin` and must provide Visual Studio integration files in path `.\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.
