开始以为是路径或者依赖库的问题，原来是opencv的版本问题。在ORB_SLAM2文件下的CMakeLists.txt文件中

find_package(OpenCV 3 QUIET)
if(NOT OpenCV_FOUND)
   find_package(OpenCV 2.4.3 QUIET)
   if(NOT OpenCV_FOUND)
      message(FATAL_ERROR "OpenCV > 2.4.3 not found.")
   endif()
endif()

原来是这样写的，但是因为我的opencv版本是3.2.0，所以它opencv3这个版本找不到。把第一个find_package(OpenCV 3 QUIET)改成find_package(OpenCV 3.2.0 QUIET)就可以了

最后收集了几个BUG的博客，感谢他们的改错成果。
