This -module does not search for the NVIDIA CUDA Samples. - -.. versionadded:: 3.19 - QNX support. - -Search Behavior -^^^^^^^^^^^^^^^ - -The CUDA Toolkit search behavior uses the following order: - -1. If the ``CUDA`` language has been enabled we will use the directory - containing the compiler as the first search location for ``nvcc``. - -2. If the variable :variable:`CMAKE_CUDA_COMPILER _COMPILER>` or - the environment variable :envvar:`CUDACXX` is defined, it will be used - as the path to the ``nvcc`` executable. - -3. If the ``CUDAToolkit_ROOT`` cmake configuration variable (e.g., - ``-DCUDAToolkit_ROOT=/some/path``) *or* environment variable is defined, it - will be searched. If both an environment variable **and** a - configuration variable are specified, the *configuration* variable takes - precedence. - - The directory specified here must be such that the executable ``nvcc`` or - the appropriate ``version.txt`` or ``version.json`` file can be found - underneath the specified directory. - -4. If the CUDA_PATH environment variable is defined, it will be searched - for ``nvcc``. - -5. The user's path is searched for ``nvcc`` using :command:`find_program`. If - this is found, no subsequent search attempts are performed. Users are - responsible for ensuring that the first ``nvcc`` to show up in the path is - the desired path in the event that multiple CUDA Toolkits are installed. - -6. On Unix systems, if the symbolic link ``/usr/local/cuda`` exists, this is - used. No subsequent search attempts are performed. No default symbolic link - location exists for the Windows platform. - -7. The platform specific default install locations are searched. If exactly one - candidate is found, this is used. The default CUDA Toolkit install locations - searched are: - - +-------------+-------------------------------------------------------------+ - | Platform | Search Pattern | - +=============+=============================================================+ - | macOS | ``/Developer/NVIDIA/CUDA-X.Y`` | - +-------------+-------------------------------------------------------------+ - | Other Unix | ``/usr/local/cuda-X.Y`` | - +-------------+-------------------------------------------------------------+ - | Windows | ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\vX.Y`` | - +-------------+-------------------------------------------------------------+ - - Where ``X.Y`` would be a specific version of the CUDA Toolkit, such as - ``/usr/local/cuda-9.0`` or - ``C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0`` - - .. note:: - - When multiple CUDA Toolkits are installed in the default location of a - system (e.g., both ``/usr/local/cuda-9.0`` and ``/usr/local/cuda-10.0`` - exist but the ``/usr/local/cuda`` symbolic link does **not** exist), this - package is marked as **not** found. - - There are too many factors involved in making an automatic decision in - the presence of multiple CUDA Toolkits being installed. In this - situation, users are encouraged to either (1) set ``CUDAToolkit_ROOT`` or - (2) ensure that the correct ``nvcc`` executable shows up in ``$PATH`` for - :command:`find_program` to find. - -Arguments -^^^^^^^^^ - -``[]`` - The ``[]`` argument requests a version with which the package found - should be compatible. See :ref:`find_package version format ` - for more details. - -Options -^^^^^^^ - -``REQUIRED`` - If specified, configuration will error if a suitable CUDA Toolkit is not - found. - -``QUIET`` - If specified, the search for a suitable CUDA Toolkit will not produce any - messages. - -``EXACT`` - If specified, the CUDA Toolkit is considered found only if the exact - ``VERSION`` specified is recovered. - -Imported targets -^^^^^^^^^^^^^^^^ - -An :ref:`imported target ` named ``CUDA::toolkit`` is provided. -
