关于win7中VS2013配置opencv2.4.13 时报CPACK_PACKAGE_VERSION错

在win7中配置opencv2.4.13 时报错  ，错误信息是：CMake Warning at cmake/OpenCVPackaging.cmake:23 (message): CPACK_PACKAGE_VERSION does not match version provided by version.hpp根据报错信息“”cmake/OpenCVPackaging.cmake:23“”错误现场信息是：  if (NOT "${OPENCV_VCSVERSION}" MATCHES "^${OPENCV_VERSION}.*")
    message(WARNING "CPACK_PACKAGE_VERSION does not match version provided by version.hpp header!")
  endif()然后去找${OPENCV_VCSVERSION}  ， ${OPENCV_VERSION} 这2个参数信息是从哪里来最后在CMakeList.txt文件中找到如下信息status("General configuration for OpenCV ${OPENCV_VERSION} =====================================")
if(OPENCV_VCSVERSION)
  status("  Version control:" ${OPENCV_VCSVERSION})
endif() 
正好是状态输出中有看到，如下General configuration for OpenCV 2.4.13 =====================================Version control: unknown
也就是对应了${OPENCV_VERSION} = 2.4.13  ，  ${OPENCV_VCSVERSION}) = unknown
继续寻找${OPENCV_VCSVERSION}) 这个参数是在哪里赋值的找找找，找到了，在这里find_host_program(GIT_EXECUTABLE NAMES ${git_names} PATH_SUFFIXES Git/cmd Git/bin DOC "git command line client")
mark_as_advanced(GIT_EXECUTABLE)

if(GIT_EXECUTABLE)
  execute_process(COMMAND ${GIT_EXECUTABLE} describe --tags --always --dirty --match "2.[0-9].[0-9]*"
    WORKING_DIRECTORY "${OpenCV_SOURCE_DIR}"
    OUTPUT_VARIABLE OPENCV_VCSVERSION
    RESULT_VARIABLE GIT_RESULT
    ERROR_QUIET
    OUTPUT_STRIP_TRAILING_WHITESPACE
  )
  if(NOT GIT_RESULT EQUAL 0)
    set(OPENCV_VCSVERSION "unknown")
  endif()
else()
  # We don't have git:
  set(OPENCV_VCSVERSION "unknown")
endif()找到CMakeList.txt文件中上述位置，将后面两个unknown改成2.4.13版本号，重新编译就OK了  if(NOT GIT_RESULT EQUAL 0)
    set(OPENCV_VCSVERSION "2.4.13")
  endif()
else()
  # We don't have git:
  set(OPENCV_VCSVERSION "2.4.13")
endif()
