NO_COLOR

.. versionadded:: 4.1

.. include:: include/ENV_VAR.rst

Set to a non-empty value, other than 0, to tell command-line tools not to print color messages even if connected to a terminal. This is a common convention_ among command-line tools in general.

See also the :envvar:CLICOLOR_FORCE and :envvar:CLICOLOR environment variables. If :envvar:!NO_COLOR is activated, it takes precedence over both of them.

See the :variable:CMAKE_COLOR_DIAGNOSTICS variable to control color in a generated build system.
