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.
