Eclipse doesn't find libnppc.so.7.0 library to run a python code, containing Opencv commands which use CUDA libraries

I have OPENCV 2.4.10 and CUDA 7.5 installed on Ubuntu 14.4 LTS.

By running a simple python code which uses opencv libraries through terminal,it works well without any problem, but when I make a Pydev Project in eclipse and make a new source python file and paste the above code in it, after running it in eclipse gives the following error.

ImportError: libnppc.so.7.0: cannot open shared object file: No such file or directory

this is the paths in .bashrc file:

# added by Anaconda 2.3.0 installer
export PATH="/home/username/anaconda/bin:$PATH"

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

export PATH="/usr/local/cuda-7.0/bin:$PATH"
export PATH="/usr/local/cuda/bin:$PATH"
export LD_LIBRARY_PATH="/usr/lib/:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/home/username/anaconda/lib:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH="/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH"
export LD_LIBRARY_PATH="/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH"

in eclipse the following path is for Python Interpreter:

/home/username/anaconda/bin

I found the solution:

Eclipse is looking for cuda folder not cuda-7.0 folder, so I had do build symbolink links of the libraries in cuda-7.0 in cuda folder as well.

this solved the problem.
