 Specify whether to treat warnings on compile as errors.
 If enabled, adds a flag to treat warnings on compile as errors.
+If the ``--compile-no-warning-as-error`` option is given on the
+:manual:`cmake(1)` command line, this property is ignored.

+This property is not implemented for all compilers.  It is silently ignored
+if there is no implementation for the compiler being used.  The currently
+implemented :variable:`compiler IDs <CMAKE_<LANG>_COMPILER_ID>` are:
+
+* ``GNU``
+* ``Clang``
+* ``AppleClang``
+* ``Fujitsu``
+* ``FujitsuClang``
+* ``IBMClang``
+* ``Intel``
+* ``IntelLLVM``
+* ``LCC``
+* ``MSVC``
+* ``NVHPC``
+* ``NVIDIA`` (CUDA)
+* ``QCC``
+* ``SunPro``
+* ``TI``
+* ``VisualAge``
+* ``XL``
+* ``XLClang``
 
 This property is initialized by the value of the variable
 :variable:`CMAKE_COMPILE_WARNING_AS_ERROR` if it is set when a target is created.
