cmake cannot find -lopencv_dep_cudart

最近在使用v4l2获取视频。在编译的过程中，遇到了下面的问题，CMakeLists代码和报错程序截图如下：

# cmake needs this line
cmake_minimum_required(VERSION 2.8.4)

# Define project name
project(capturev4l2)

# Find OpenCV
find_package(OpenCV REQUIRED)

# Add OpenCV headers location to your include paths
include_directories(${OpenCV_INCLUDE_DIRS})

# Declare the executable target built from your sources
set(SOURCE capturev4l2.c)
add_executable(capturev4l2 ${SOURCE})

# Link your application with OpenCV libraries
target_link_libraries(capturev4l2 ${OpenCV_LIBS})

发现上面的错误提示有关于cuda，cmake cannot find -lopencv_dep_cudart。添加了cuda的CMakeLists依赖之后代码如下

# cmake needs this line
cmake_minimum_required(VERSION 2.8.4)

# Define project name
project(capturev4l2)

# Find OpenCV
find_package(OpenCV REQUIRED)
find_package(CUDA)

# Add OpenCV headers and cuda header location to your include paths
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories("/usr/local/cuda-8.0/include")

# Declare the executable target built from your sources
set(SOURCE capturev4l2.c)
add_executable(capturev4l2 ${SOURCE})

# Link your application with OpenCV libraries
target_link_libraries(capturev4l2 ${OpenCV_LIBS})

编译

$cmake ..
$make

最后在https://devtalk.nvidia.com/default/topic/970325/jetson-tx1/cmake-cannot-find-lopencv_dep_cudart/发现有人遇到了同样的问题。在CMakeLists加入下面这行代码

set(CUDA_USE_STATIC_CUDA_RUNTIME OFF)

编译成功。
