New in version 3.16.
The ObjC++ standard whose features are requested to build this target.
This property specifies the ObjC++ 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
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:
set_property(TARGET tgt PROPERTY OBJCXX_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
OBJCXX_STANDARD_REQUIRED target property. Additionally, the
OBJCXX_EXTENSIONS target property may be used to control whether compiler-specific extensions are enabled on a per-target basis.

This property is initialized by the value of the
CMAKE_OBJCXX_STANDARD variable if it is set when a target is created.
