如何在Ubuntu11.10上使用cuda和opencv

我想在ubuntu上运行surfgpu。但不知道如何编写CmakeList。我已经安装了CUDA 4.2 SDK和工具包，程序中的C可以运行。我的开发环境是Qt.ubuntu 11.10。opencv2.4.2非常感谢任何好的建议。

这个怎么样

# CMakeLists.txt to build OpenCV project
cmake_minimum_required(VERSION 2.8)
project( testOpenCV )

查找OpenCV和CUDA包

find_package(OpenCV REQUIRED )
find_package(CUDA 4.2 REQUIRED)

从一些目录中包括

# Since surf is a non free package, you also have to add non free include dir
include_directories( ${OpenCV_INCLUDE_DIR} "${OpenCV_SOURCE_DIR}/modules/nonfree/include" ${CUDA_INCLUDE_DIRS})

编译源代码

cuda_add_executable( exefile source.cpp source2.cpp )
target_link_libraries( exefile ${OpenCV_LIBS} ${otherlibsyouneed} )

只有使用

-DHAVE\u CUDA
