我正在实施视频拼接纸并使用CMake生成make文件。看起来CMake在使用OpenCV的拼接模块（特别是搅拌器部件）编译代码时，无法为编译器传递正确的args。 make进度因此错误而停止：

我的CMake如下所示：
CMAKE_MINIMUM_REQUIRED (VERSION 3.2)
PROJECT(VideoStitcher CXX)
FIND_PACKAGE(OpenCV REQUIRED)
INCLUDE_DIRECTORIES(include)
SET(CMAKE_CXX_STANDARD 11)
SET(CMAKE_VERBOSE_MAKEFILE ON)
if(NOT CMAKE_BUILD_TYPE)
SET(CMAKE_BUILD_TYPE Release)
endif()
SET(CMAKE_CXX_FLAGS "-Wall -Wextra")
FILE(GLOB all_sources "src/*.cpp")
ADD_EXECUTABLE(stitcher ${all_sources})
TARGET_LINK_LIBRARIES(
stitcher
boost_filesystem
boost_system
${OpenCV_LIBS}
)
这很奇怪，因为OpenCV成功构建了所有CPP示例，我甚至可以使用类似于上面的CMake构建 stitching_detailed.cpp 示例。以下是我的OpenCV构建信息：

我尝试了各种方法将CUDA添加到CMake但没有运气。我也无法在互联网上找到类似的问题。
