Unsupported gpu architecture 'compute_11'解决方法

环境背景:
由于项目需要，在ubuntu service 14.04 下搭建 OpenCL +OpenCV 环境， 前期安装了 CUDA7.0 ，GPU为 NVIDIA TITAN 。

问题描述：
按照网上教程安装OpenCV ，在make 时出现错误，错误提示如下:错误提示

nvcc fatal   : Unsupported gpu architecture 'compute_11'
CMake Error at cuda_compile_generated_matrix_operations.cu.o.cmake:206 (message):

make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs....

解决方法:
百度无果，求助万能谷歌。有高人回答如下:

    When using cmake to do configurations, set the option CUDA_GENERATION to specific your GPU architecture. I ran across the same error and tried this to work out the problem.
    this worked for me and shows a possible value for CUDA_GENERATION:
    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..

然后，这个问题就奇迹般的解决了。
总结:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D CUDA_GENERATION=Kepler ..

This let me install opencv-2.4.9.
