Error during installation does not find file libopencv_core.so.2.4.0

edit

I received this error during installation on Lubuntu 14:04

CMake Error at modules/core/cmake_install.cmake:48 (FILE):
  file INSTALL cannot find
  "/home/julio/Downloads/OpenCV-2.4.0/release/build/lib/libopencv_core.so.2.4.0".
Call Stack (most recent call first):
  modules/cmake_install.cmake:57 (INCLUDE)
  cmake_install.cmake:55 (INCLUDE)

Has two links that do not have the files they point to.

libopencv_core.so -> libopencv_core.so.2.4
libopencv_core.so.2.4 -> libopencv_core.so.2.4.0

Does anyone know how I can fix? Forgive my English is not very good. I thank you.
