Configuration of OpenCV on Mac OSX with CUDA is broken (again) in 2.4.9
(it worked fine on my machine in 2.4.8).

During ccmake, I have the following warning :
<pre>
CMake Warning (dev) at cmake/OpenCVDetectCUDA.cmake:245 (link_directories):
This command specifies the relative path

-Wl,/usr/local/cuda

as a link directory.

Policy CMP0015 is not set: link_directories() treats paths relative to the
source dir. Run "cmake --help-policy CMP0015" for policy details. Use the
cmake_policy command to set the policy and suppress this warning.
Call Stack (most recent call first):
cmake/OpenCVFindLibsPerf.cmake:24 (include)
CMakeLists.txt:468 (include)
This warning is for project developers. Use -Wno-dev to suppress it.
</pre>

During compilation (make VERBOSE=1), I get the following error :
<pre>

Details of my configuration :
OS X 10.9.4
cmake 2.8.12.2
clang: Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
CUDA Driver version: 6.0.54
