Hello,
I am trying to build opencv version 2.4.10 with CUDA 7 on ubuntu 16.04.
Getting stuck at linking stage with the following settings:
cmake -D CMAKE_BUILD_TYPE=Release
-D CMAKE_INSTALL_PREFIX=/usr/local
-D BUILD_TIFF=ON
-D BUILD_EXAMPLES=OFF
-D BUILD_TESTS=OFF
-D BUILD_NEW_PYTHON_SUPPORT=ON
-D CUDA_GENERATION=Kepler
-DCUDA_USE_STATIC_CUDA_RUNTIME=OFF
-D BUILD_PERF_TESTS=OFF
-DCUDA_NVCC_FLAGS="-D_FORCE_INLINES" ..
It took me a while to find all these settings which were necessary to at least get to the linking stage. All the tests and examples are off so it will take a little less time to finally get to the next error after every attempt.
In any case, here is the error I am now stuck with:

I am not sure what to try next, and will appreciate any clue.
Thanks!
