CMake Cookbook

How to do it

We will follow these steps to register the version in our template header file:

1. To track the code version, we can define the project version when invoking the CMake project command in CMakeLists.txt:

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)project(recipe-04 VERSION 2.0.1 LANGUAGES C)

2. We then configure version.h, based on version.h.in:

configure_file(  version.h.in  generated/version.h  @ONLY  )

3. Finally, we define the executable and provide the target include path:

add_executable(example example.c)target_include_directories(example  PRIVATE    ${CMAKE_CURRENT_BINARY_DIR}/generated  )
