OpenCV 3.0 源代码安装故障排除

我使用从itseez github存储库获得的源代码安装了OpenCV3.0。我将安装前缀设置为 /home/ubuntu/installed_libs/ .一切都很顺利。我什至在 /etc/ld.so.conf.d/local.conf 中设置了 ldconfig 路径，然后sudo ldconfig.

但是在我的项目（CMake）中，我找不到新安装的目录。

当我在构建目录中cmake ../时，它会抛出以下错误。我按照答案中的建议做了一些更改。

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}")

现在cmake成功了。

 $ cmake ..

但是，当我执行make时，出现错误：

我知道这是一个链接错误。我应该如何解决这个问题？

详细显示以防万一有帮助。
