A common anti-pattern is to copy from the `CUDA_ARCHITECTURES` documentation. If at any point the user tries to simplify by changin `set_property` to `set_target_properties` the code breaks. To better train users, provide and example of how to set multiple CUDA architectures with `set_target_properties`.

CUDA_ARCHITECTURES

------------------
|
|
|
|
.. versionadded:: 3.18
|
|
|
|
List of architectures to generate device code for.
|
|
|
|
An architecture can be suffixed by either ``-real`` or ``-virtual`` to specify
|
|
the kind of architecture to generate code for.
|
|
If no suffix is given then code is generated for both real and virtual
|
|
architectures.
|
|
|
|
A non-empty false value (e.g. ``OFF``) disables adding architectures.
|
|
This is intended to support packagers and rare cases where full control
|
|
over the passed flags is required.
|
|
|
|
This property is initialized by the value of the :variable:`CMAKE_CUDA_ARCHITECTURES`
|
|
variable if it is set when a target is created.
|
|
|
|
The ``CUDA_ARCHITECTURES`` target property must be set to a non-empty value on targets
|
|
that compile CUDA sources, or it is an error. See policy :policy:`CMP0104`.

Examples
|
|
^^^^^^^^
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_target_properties(tgt PROPERTIES CUDA_ARCHITECTURES "35;50;72")
|
|
|
|
Generates code for real and virtual architectures ``30``, ``50`` and ``72``.
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_property(TARGET tgt PROPERTY CUDA_ARCHITECTURES 70-real 72-virtual)
|
|
|
|
Generates code for real architecture ``70`` and virtual architecture ``72``.
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_property(TARGET tgt PROPERTY CUDA_ARCHITECTURES OFF)
|
|
|
|
CMake will not pass any architecture flags to the compiler.
