after building finish i try to compile an c++ code as static lib and this is my

CMakeListed.txt file 

    cmake_minimum_required(VERSION 2.8)                     
   PROJECT(word)              
   set(OpenCV_DIR "/home/medozeus/videos/opencv/share/opencv")                     
   FIND_PACKAGE( OpenCV REQUIRED )                               
   INCLUDE_DIRECTORIES( ${OpenCV_INCLUDE_DIRS} )
   ADD_EXECUTABLE(wordx main.cpp)                          
   TARGET_LINK_LIBRARIES (wordx ${OpenCV_LIBS})

its compiled without error and i run the program also without error but when i send the program to another pc and run it its give me

error while loading shared libraries: libjpeg.so.8: cannot open shared object file: No such file or directory

The error means there is no libjpeg.so.8 file on target machine you are running your executable. You could try installing it:

sudo apt-get install libjpeg-dev

    Just to add a little bit more to your answer, OpenCV has quite a lot of dependencies (a lot of them optional), but I will suggest @medo to take a look to this [tutorial](http://www.pyimagesearch.com/2016/10/24/ubuntu-16-04-how-to-install-opencv/) to the part of the dependencies, to be able to install the most used ones – api55 Sep 04 '17 at 13:33
