OpenCV 3.0 source code installation troubleshooting - c++

Question

I installed OpenCV3.0 using the source code obtained from itseez github repo. I set the install prefix as /home/ubuntu/installed_libs/. All went well. I even set ldconfig path in /etc/ld.so.conf.d/local.conf and then sudo ldconfig.
However in my project (CMake) I cannot find the newly installed directory.
When I do cmake ../ in the build directory it throws the following error.
I did some changes as suggested in the answers.
cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
set(OpenCV_DIR /home/ubuntu/installed_libs/share/OpenCV)
find_package( OpenCV )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBRARIES} )
message(STATUS "OpenCV_FOUND=${OpenCV_FOUND}")
message(STATUS "OpenCV_INCLUDES=${OpenCV_INCLUDE_DIR}")
message(STATUS "OpenCV_LIBRARIES=${OpenCV_LIBRARIES}")
message(STATUS "OpenCV_DEFINATIONS=${OpenCV_DEFINATIONS}")
message(STATUS "OpenCV_DIR=${OpenCV_DIR}")
Now cmake happens successfully.
$ cmake ..

However, when I do a make, I get an error :

I know this is a linking error. How should I fix this?
Verbose make display incase it is helpful.

Answer 1

You should check the output of:
ldconfig -p | grep -i opencv
pkg-config --cflags opencv
pkg-config --libs opencv
If nothing is listed, then you ldconfig may configured incorrectly. If the system-installed version of OpenCV is listed, it may be a problem of the search order.
In either case, you could try to configure the CMAKE_MODULE_PATH of your project DisplayImage, which is searched by CMake before standard system locations. So, assuming your in your build directory of DisplayImage is $SRC_DIR/build, configure your project like this
cmake -DCMAKE_MODULE_PATH="/home/ubuntu/installed_libs/<OpenCV directory>" <other options> ..
Also interesting: what happens in the background of find_package().

Answer 2

You can add
set(OpenCV_DIR /home/ubuntu/installed_libs/share/OpenCV)
to your CMakeLists, so it looks something like
cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
set(OpenCV_DIR /home/ubuntu/installed_libs/share/OpenCV)
find_package( OpenCV REQUIRED 3.0 )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )
