- [Instructor] Custom commands are a powerful feature in CMake that let us extend our build process beyond just compiling code. They are essential for real world projects where you need to generate files, process resources, or run scripts as part of your build. In this video, we'll create a custom command that generates a text file containing real project and build information. We'll keep working with the top level CMakeLists.txt file. Use add_custom_command to create a, well, custom command. Next, the OUTPUT command tells CMake to generate a file called build_info.txt in the top level build folder. The first command writes the text ImageLite Build Information to the file. Note that we're using add_custom_command with CMake's built-in -E script mode commands, which are intentionally designed to be cross-platform. The second command appends the CMake version after it.
