当编译opencv3.1.0--opencv-contribute3.1.0的时候会出现 这样的问题：
CMake Error in CMakeLists.txt: Imported target "opencv_xphoto" includes non-existent path "xxxxxxxxxxxxxxxxx/x64/vc14/lib/include" in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include:
* The path was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully. * The installation package was faulty and references files it does not provide.
这是由于配置 OpenCV_CONFIG_PATH 实际上是
xxxxxxxxxxxxxxxxx/x64/vc14/lib
造成的
opencv3.x opencv2.x opencv4.x 的cmake文件都有一些不一样的。
解决办法：
修改 D:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx64vc14lib/OpenCVConfig.cmake
# Provide the include directories to the caller # set(OpenCV_INCLUDE_DIRS "${OpenCV_CONFIG_PATH}/include" "${OpenCV_CONFIG_PATH}/include/opencv") set(OpenCV_INCLUDE_DIRS "${OpenCV_CONFIG_PATH}/../../../include" "${OpenCV_CONFIG_PATH}/../../../include/opencv")
修改之后的编译：
顺便贴出我的文件：（实际上也可以加入打印语句，让错误无所遁形。）
