For opencv2 / xfeatures2d / cuda.hpp: Solution No such file or directory type of problem

1. /usr/local/arm/opencv-3.4.0/opencv_contrib-3.4.0/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp:42:10:

2. fatal error: /opencv2/xfeatures2d.hpp: No such file or directory

3. #include "/opencv2/xfeatures2d.hpp"

4. ^~~~~~~~~~~~~~~~~~~~~~~~~~

5. compilation terminated.

To find a path to a file and open xfeature2d.hpp, locate line 42 as follows:

1. 40 #ifndef __OPENCV_XFEATURES2D_HPP__

2. 41 #define __OPENCV_XFEATURES2D_HPP__

3.  

4. 42 #include"/opencv2/xfeatures2d.hpp"

Instead the absolute path

1. 40 #ifndef __OPENCV_XFEATURES2D_HPP__

2. 41 #define __OPENCV_XFEATURES2D_HPP__

3.  

4. 42#include"/usr/local/arm/opencv3.4.0/opencv_contrib3.4.0/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp"

All this can not be found are so resolved.
