HIP_STANDARD
------------
.. versionadded:: 3.21
The HIP/C++ standard requested to build this target.
Supported values are:
``98``
HIP C++98
``11``
HIP C++11
``14``
HIP C++14
``17``
HIP C++17
``20``
HIP C++20
``23``
HIP C++23
``26``
.. versionadded:: 3.25
HIP C++26. CMake 3.25 and later *recognize* ``26`` as a valid value,
no version has support for any compiler.
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 HIP_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:`HIP_STANDARD_REQUIRED` target property.
Additionally, the :prop_tgt:`HIP_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_HIP_STANDARD` variable if it is set when a target
is created.
