FindCUDAToolkit
|
|
---------------
|
|
|
|
.. versionadded:: 3.17
|
|
|
|
This script locates the NVIDIA CUDA toolkit and the associated libraries, but
|
|
does not require the ``CUDA`` language be enabled for a given project. 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 ``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.
|
|
|
|
3. If the CUDA_PATH environment variable is defined, it will be searched
|
|
for ``nvcc``.
|
|
|
|
4. 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.
|
|
|
|
5. 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.
|
|
|
|
6. 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
|
|
^^^^^^^^^
|
|
|
|
``[<version>]``
|
|
The ``[<version>]`` argument requests a version with which the package found
|
|
should be compatible. See :ref:`find_package version format <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.
|
|
|
|

|
``CUDAToolkit_VERSION_PATCH``
|
|
The patch version of the CUDA Toolkit.
|
|
|
|
``CUDAToolkit_BIN_DIR``
|
|
The path to the CUDA Toolkit library directory that contains the CUDA
|
|
executable ``nvcc``.
|
|
|
|
``CUDAToolkit_INCLUDE_DIRS``
|
|
The path to the CUDA Toolkit ``include`` folder containing the header files
|
|

|
|
|
|
``CUDAToolkit_LIBRARY_DIR``
|
|
The path to the CUDA Toolkit library directory that contains the CUDA

|
Runtime library ``cudart``.

|
|

``CUDAToolkit_LIBRARY_ROOT``

|
``CUDAToolkit_TARGET_DIR``
|
|
The path to the CUDA Toolkit directory including the target architecture

|
the parent directory of ``CUDAToolkit_BIN_DIR``.
|

The path to the NVIDIA CUDA compiler ``nvcc``. Note that this path may
|
|
**not** be the same as
|
|
:variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>`. ``nvcc`` must be
|
|
found to determine the CUDA Toolkit version as well as determining other
|
|
features of the Toolkit. This variable is set for the convenience of
|
|
modules that depend on this one.
