This "decay" behavior may be controlled with the :prop_tgt:`<LANG>_STANDARD_REQUIRED` target property. +Note that the actual language standard used may be higher than that specified +by ``<LANG>_STANDARD``, regardless of the value of +:prop_tgt:`<LANG>_STANDARD_REQUIRED`. In particular, +:ref:`transitive usage requirements <Target Usage Requirements>` or the use of +:manual:`compile features <cmake-compile-features(7)>` can raise the required +language standard above what ``<LANG>_STANDARD`` specifies. + These properties are initialized by the value of the :variable:`CMAKE_<LANG>_STANDARD` variable if it is set when a target is created. |
