This is how we can use the color definitions to generate colored status messages:

1. We start out with a familiar preamble:

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)
  
project(recipe-02 LANGUAGES NONE)

2. Then, we append the cmake subdirectory to the list of module paths that CMake will search:

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake")

3. We then include the colors.cmake module and call the macro defined within:

include(colors)
define_colors()

4. Finally, we print a couple of messages in different colors:

message(STATUS "This is a normal message")
message(STATUS "${Red}This is a red${ColourReset}")
message(STATUS "${BoldRed}This is a bold red${ColourReset}")
message(STATUS "${Green}This is a green${ColourReset}")
message(STATUS "${BoldMagenta}This is bold${ColourReset}")

5. Let us test it out (this output should appear colored on your screen if you use macOS or Linux):
