lsd_SLAM Ubuntu16编译问题集锦

1。/usr/lib/x86_64-linux-gnu/libboost_system.so.1.54.0:-1: error: error adding symbols: DSO missing fro
boost filesystem

boost.filesystem处理目录确实方便，于是本人使用cmake来加载的boost，但使用filesystem出现这一bug。

上网google，别人说要加上"-lboost_system"，但我添加上仍然不好使用。
最后，抱着试试的心态使用了
target_link_libraries(ABC boost_system boost_filesystem)  
2。编译时出现下列错误：error: undefined reference to `cv::imread(cv::String const&, int)'

    undefined reference to 'cv::imread(cv::String const&, int)'
    undefined reference to 'cv::String::deallocate()'
    undefined reference to 'cv::imread(cv::String const&, int)'
    undefined reference to 'cv::String::deallocate()'
    undefined reference to 'cv::String::allocate(unsigned long)'
    undefined reference to 'cv::String::allocate(unsigned long)'
    undefined reference to 'cv::String::deallocate()'
    undefined reference to 'cv::String::deallocate()'

    解决方法：在CMakeLists.txt加入安装OpenCV的版本号：
    将
    find_package( OpenCV REQUIRED )
    更改为
    find_package( OpenCV 3 REQUIRED ) 。

3。Could not find a package configuration file – OpenCVConfig.cmake
  I am playing nowadays with OpenCV for visual computing usin
