error while re-build opencv-3.1.0 with extra modules "opencv_contrib" ?

edit

I'm using Opencv 3.1.0 on Ubuntu 14.04

after downloading opencv_contrib then moving the folder to /home/MY_NAME/opencv-3.1.0/build then type in terminal cmake -DOPENCV_EXTRA_MODULES_PATH=opencv_contrib/modules opencv_source_directory

I had this error "bash: /modules: Permission denied"

then I've changed the permission to both opencv_contrib/modules & build/modules with chmod 777 FileName

then logout to know if anything changes

Unfortunately, I still have this error "bash: /modules: Permission denied"

solve this, but after typing the absolute path :

cmake -DOPENCV_EXTRA_MODULES_PATH=/home/mohammed-aboelias/opencv_contrib/modules ..

I had this on the terminal :
