When crosscompiling we pass the sysroot.
We need to try various architecture flags. Clang doesn't automatically
select one that works. First try the ones that are more likely to work
for modern installations:
* <=sm_50 is deprecated since CUDA 10.2, try sm_52 first for
future compatibility.
* <=sm_20 is removed since CUDA 9.0, try sm_30.
Otherwise fallback to Clang's current default. Currently that's `sm_20`,
the lowest it supports.
Separable compilation isn't supported yet.
Fixes: #16586

CUDA_STANDARD
|
|
-------------
|
|
|
|
The CUDA/C++ standard whose features are requested to build this target.
|
|
|
|
This property specifies the CUDA/C++ standard whose features are requested
|
|
to build this target. For some compilers, this results in adding a
|
|
flag such as ``-std=gnu++11`` to the compile line.
|
|
|
|
Supported values are ``98``, ``03``, ``11``, ``14``, ``17``, ``20``.
|
|
|
|
If the value requested does not result in a compile flag being added for
|
|
the compiler in use, a previous standard flag will be added instead. This
|
|
means that using:
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_property(TARGET tgt PROPERTY CUDA_STANDARD 11)
|
|
|
|
with a compiler which does not support ``-std=gnu++11`` or an equivalent
|
|
flag will not result in an error or warning, but will instead add the
|
|
``-std=gnu++98`` flag if supported. This "decay" behavior may be controlled
|
|
with the :prop_tgt:`CUDA_STANDARD_REQUIRED` target property.
|
|
Additionally, the :prop_tgt:`CUDA_EXTENSIONS` target property may be used to
|
|
control whether compiler-specific extensions are enabled on a per-target basis.
|
|
|
|
See the :manual:`cmake-compile-features(7)` manual for information on
|
|
compile features and a list of supported compilers.
|
|
|
|
This property is initialized by the value of
|
|
the :variable:`CMAKE_CUDA_STANDARD` variable if it is set when a target
|
|
is created.
