How to do it
The following illustrates the steps to record versioning information from Git:

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)project(recipe-06 LANGUAGES CXX)set(CMAKE_CXX_STANDARD 11)set(CMAKE_CXX_EXTENSIONS OFF)set(CMAKE_CXX_STANDARD_REQUIRED ON)
- We then use the following code snippet to define a variable, GIT_HASH:
# in case Git is not available, we default to "unknown"set(GIT_HASH "unknown")# find Git and if available set GIT_HASH variablefind_package(Git QUIET)if(GIT_FOUND) execute_process( COMMAND ${GIT_EXECUTABLE} log -1 --pretty=format:%h OUTPUT_VARIABLE GIT_HASH OUTPUT_STRIP_TRAILING_WHITESPACE ERROR_QUIET WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
