# CUDA_RUNTIME_LIBRARY

Select the CUDA runtime library for use by compilers targeting the CUDA language.

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 `CUDA_RUNTIME_LIBRARY` may use `generator expressions`.

If that property is not set then CMake uses an appropriate default value based on the compiler 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.
