C_STANDARD

C_STANDARD

The C standard whose features are requested to build this target.

This property specifies the C standard whose features are requested to build this target. For some compilers, this results in adding a flag such as -std=gnu11 to the compile line. For compilers that have no notion of a standard level, such as MSVC, this has no effect.

Supported values are 90, 99 and 11.

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 C_STANDARD 11)

with a compiler which does not support -std=gnu11 or an equivalent flag will not result in an error or warning, but will instead add the -std=gnu99 or -std=gnu90 flag if supported. This “decay” behav
