获取当前版本哈希值
<code>
git rev-parse --short HEAD

macro(get_git_hash _git_hash)
    find_package(Git QUIET)
    if(GIT_FOUND)
      execute_process(
        COMMAND ${GIT_EXECUTABLE} rev-parse --short HEAD
        OUTPUT_VARIABLE ${_git_hash}
        OUTPUT_STRIP_TRAILING_WHITESPACE
        ERROR_QUIET
        WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
      )
    endif()
endmacro()
</code>

获取当前版本提交序号：(类似SVN的全局版本号revision)
<code>
git rev-list --count HEAD

macro(get_git_rev _git_rev)
    find_package(Git QUIET)
    if (GIT_FOUND)
        execute_process(
            COMMAND ${GIT_EXECUTABLE} rev-list --count HEAD
            OUTPUT_VARIABLE ${_git_rev}
            OUTPUT_STRIP_TRAILING_WHITESPACE
            ERROR_QUIET
            WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
        )
    endif()
endmacro()
</code>
