While we could do this exclusively in the source code, using -CMakeLists provides more flexibility. - -To add a version number we modify the CMakeLists file as follows: - - cmake_minimum_required(VERSION 3.3) - project(Tutorial) - - # the version number. - set(Tutorial_VERSION_MAJOR 1) - set(Tutorial_VERSION_MINOR 0) - - # configure a header file to pass some of the CMake settings - # to the source code - configure_file( - "${PROJECT_SOURCE_DIR}/TutorialConfig.h.in" - "${PROJECT_BINARY_DIR}/TutorialConfig.h" - ) - - # add the executable - add_executable(Tutorial tutorial.cxx) - - # add the binary tree to the search path for include files - # so that we will find TutorialConfig.h - target_include_directories(Tutorial PUBLIC - "${PROJECT_BINARY_DIR}" - ) - - -We then create a TutorialConfig.h.in file in the source tree with the -following contents: - - // the configured options and settings for Tutorial - #define Tutorial_VERSION_MAJOR @Tutorial_VERSION_MAJOR@ - #define Tutorial_VERSION_MINOR @Tutorial_VERSION_MINOR@ - -When CMake configures this header file the values for @Tutorial_VERSION_MAJOR@ -and @Tutorial_VERSION_MINOR@ will be replaced by the values from the CMakeLists -file.
