Added in version 3.24.
Enable color diagnostics throughout.
This variable uses three states: ON
, OFF
and not defined.
When not defined:
Makefile Generators initialize the CMAKE_COLOR_MAKEFILE
variable to ON
. It controls color buildsystem messages.
GNU/Clang compilers are not invoked with any color diagnostics flag.
When ON
:
Makefile Generators produce color buildsystem messages by default.
CMAKE_COLOR_MAKEFILE
is not initialized, but may be
explicitly set to OFF
to disable color buildsystem messages.
GNU/Clang compilers are invoked with a flag enabling color diagnostics
(-fcolor-diagnostics
).
When OFF
:
Makefile Generators do not produce color buildsystem messages by
default. CMAKE_COLOR_MAKEFILE
is not initialized, but may be
explicitly set to ON
to enable color buildsystem messages.
GNU/Clang compilers are invoked with a flag disabling color diagnostics
(-fno-color-diagnostics
).
If the CMAKE_COLOR_DIAGNOSTICS
environment variable is set, its
value is used. Otherwise, CMAKE_COLOR_DIAGNOSTICS
is not defined by
default.
