If you do the following, you will be able to use opencv build from OpenCV_INSTALL_PATH.

cmake_minimum_required(VERSION 2.8)

SET(OpenCV_INSTALL_PATH /home/user/opencv/opencv-2.4.13/release/)

SET(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")

SET(OpenCV_LIB_DIR "${OpenCV_INSTALL_PATH}/lib")

LINK_DIRECTORIES(${OpenCV_LIB_DIR})

set(OpenCV_LIBS opencv_core opencv_imgproc opencv_calib3d opencv_video opencv_features2d opencv_ml opencv_highgui opencv_objdetect opencv_contrib opencv_legacy opencv_gpu)

# find_package( OpenCV )

project(edge.cpp)

add_executable(edge edge.cpp)
