With this fix there is no need to add includes by using
`include_directories(${OpenCV_INCLUDE_DIRS})`. Directory will be added by
command `target_link_libraries(... ${OpenCV_LIBS})` automatically.
The use of built-in CMAKE_CURRENT_LIST_DIR requires at least
CMake 2.8.3. This fix properly defines the variable to allow its
use in versions < 2.8.3 as well.
Fixes issue #4205.
Exclude >= 2.8.3 from reimplementation of CMAKE_CURRENT_LIST_DIR
This avoids violation of possible future CMake policy checks
regarding reserved/read-only variables.
This retains the desirable quality of not including paths to CUDA libraries
from the build system into the config files, and has two major advantages:
* It removes the need to use link_directories, which doesn't guarantee that
the libraries from the supplied directory will be used (there may be
libraries with the same names earlier in the search path).
* It removes the need to put -L entries into OPENCV_LINKER_LIBS. This variable
is used with target_link_libraries, where such entries are treated as linker
flags, so doing this is unportable. I remove the support for -L entries
from OpenCVGenPkgconfig.cmake, as well, to discourage adding them in the
future.

This line causes the following error when building custom projects that use OpenCV beta 3:
ld: warning: directory not found for option '-L/<project_root>/-Wl,/usr/local/cuda'
"TRUE"/"FALSE" should not be used as literals, as CMake has to decide
whether they are literals or variable names (sigh).
This patch should make it work with any version of CMake and with any
user-side decision on old vs. new policy behavior.
I didn't make the status part of the version variables here, because
letters don't play too well with version comparison algorithms
(especially with CMake's, which only supports numbers).
find_package(OpenCV) should not include_directories by default, that is not standard afaik. Plus that creates problems when creating the ROS package :)
* fix path to libraries in Android SDK
* allow to link to opencv_java.so as Android.mk does
To link to opencv_java.so you can either change your cmake to find OpenCV as
find_package(OpenCV opencv_java)
or pass -DOpenCV_FIND_COMPONENTS=opencv_java to your cmake command
