NO_COLOR

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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 CLICOLOR_FORCE and CLICOLOR environment variables. If NO_COLOR is activated, it takes precedence over both of them.

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