# CMAKE_CUDA_RUNTIME_LIBRARY

Select the CUDA runtime library for use by compilers targeting the MSVC ABI. This variable is used to initialize the `CUDA_RUNTIME_LIBRARY` property on all targets as they are created.

The allowed case insensitive values are:

`None`
  Link with `-cudart=none` or equivalent flag(s) to use no CUDA runtime library.
`Shared`
  Link with `-cudart=shared` or equivalent flag(s) to use a dynamically-linked CUDA runtime library.
`Static`
  Link with `-cudart=static` or equivalent flag(s) to use a statically-linked CUDA runtime library.

Contents of `CMAKE_CUDA_RUNTIME_LIBRARY` may use `generator expressions`.

If this variable is not set then the `CUDA_RUNTIME_LIBRARY` target property will not be set automatically. If that property is not set then CMake uses the default value `Static` to select the CUDA runtime library.

Note

This property has effect only when the `CUDA` language is enabled. To control the CUDA runtime linking when only using the CUDA SDK with the `C` or `C++` language we recommend using the `FindCUDAToolkit` module.
