Script for automatically using OpenCV with gcc and CMake (Patch #2664)

Usage: ./script filename.cpp

Description:
The script creates the necessary CMakeLists.txt file needed for cmake configuration. Next to that, it makes a new directory called 'build' and puts there all the files produced after cmake. Then it compiles the filename.cpp and finally copies the executable file back to the original directory. So, that's an easy way for starters with OpenCV to build and run their "hello OpenCV" applications using gcc and CMake.

Script Source Code:

#!/bin/bash

app=`echo $1 | awk -F "." '{ print $1 }'`;

if [ -f CMakeLists.txt ]
then
    mv CMakeLists.txt CMakeLists.txt.old
    echo Old CMakeLists.txt has renamed as CMakeLists.txt.old
    rm CMakeLists.txt
fi
    touch CMakeLists.txt
    echo -e "cmake_minimum_required(VERSION 2.6)" >> CMakeLists.txt
    echo -e "project( $app )" >> CMakeLists.txt
    echo -e "find_package( OpenCV REQUIRED )" >> CMakeLists.txt
    echo -e "add_executable( $app $app.cpp )" >> CMakeLists.txt
    echo -e "target_link_libraries( $app \${OpenCV_LIBS} )" >> CMakeLists.txt
echo CMakeLists.txt has been created!
mkdir build
cd build
cmake ..
make
cp $app ..
cd ..
