Question

我正在开发一个项目，我想添加OpenCV。我下载了预构建的opencv 3.3.1库和最新版本的cmake。此外，我在x64调试模式的Windows x64操作系统上使用Visual Studios 2017。

CMake可以毫无错误地构建所有内容。但是，当我想在VS或调试中构建我的项目时，我收到一个致命的链接错误：

致命错误LNK1104：无法打开文件'C：\ OpenCV 3.3.1 \ opencv \ build \ lib \ Debug \ opencv_world331d.lib'

所以我检查了lib文件的目录。但目录和lib文件都不存在。

我在我的CMakeLists.txt下方附上：

SET( CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_CURRENT_SOURCE_DIR}" )
FIND_PACKAGE( KinectSDK2 REQUIRED )
INCLUDE_DIRECTORIES( ${KinectSDK2_INCLUDE_DIRS} )
LINK_DIRECTORIES( ${KinectSDK2_LIBRARY_DIRS} ) 
SET( CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}" )
FIND_PACKAGE( PCL 1.8.1 REQUIRED )
INCLUDE_DIRECTORIES( ${PCL_INCLUDE_DIRS} )
LINK_DIRECTORIES( ${PCL_LIBRARY_DIRS} )
FIND_PACKAGE( OpenCV REQUIRED )
INCLUDE_DIRECTORIES( ${OpenCV_INCLUDE_DIRS} )
LINK_DIRECTORIES( ${OpenCV_LIBRARY_DIRS} )
MESSAGE(STATUS "OpenCV library status:")
MESSAGE(STATUS "    version: ${OpenCV_VERSION}")
MESSAGE(STATUS "    libraries: ${OpenCV_LIBS}")
MESSAGE(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")
ADD_DEFINITIONS(-D_CRT_SECURE_NO_WARNINGS)
FILE( GLOB DesiredView_SRC
    "*.h"
    "*.cpp"
)
ADD_EXECUTABLE( DesiredView ${DesiredView_SRC} )

TARGET_LINK_LIBRARIES( DesiredView ${PCL_LIBRARIES} ${KinectSDK2_LIBRARIES} ${OpenCV_LIBS} )

我刚开始与CMake合作2天前。所以我对此很新。

我非常感谢任何帮助。
