Problem 'Installing' OpenCV Ubuntu 13.10

edit

I recently found a paper with source code avaiable so I've been trying to get this to run; I believe I installed OpenCV itself correctly but when I try to use CMake to generate the proper makefiles for the code I'm trying to run, I get the following error.

        CMake Error at CMakeLists.txt:15 (find_package):
      Found package configuration file:

        /home/nitin/Documents/Research/SIFT/code/opencv/release/OpenCVConfig.cmake

      but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be
      NOT FOUND.

-- Configuring incomplete, errors occurred!

Can someone shed some light on this situation? The only line in that cmake file that changes OpenCV_FOUND is:

if(ANDROID AND OpenCV_ANDROID_NATIVE_API_LEVEL GREATER ANDROID_NATIVE_API_LEVEL)
  ...
  set(OpenCV_FOUND "OpenCV_FOUND-NOTFOUND")
  ...
endif()
