最近老衛在研究c++下的opencv，發現其配置cmakelists.txt有些麻煩，遂將此分享出來，供大家使用

cmake_minimum_required(VERSION 3.9)   ##將其改為自己的版本號

project(opencv_test)   ##改為自己的專案名稱

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")  ##改為自己的c++版本號

# Where to find CMake modules and OpenCV

set(OpenCV_DIR "D:\\opencv3.2\\opencv\\mingw-build")    ##改為自己的opencv的build路徑，就是我們在cmake-gui中的輸出資料夾

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/")

find_package(OpenCV REQUIRED)

include_directories(${OpenCV_INCLUDE_DIRS})  

add_executable(opencv_test main.cpp)  ##改為自己的專案名稱

# add libs you need

set(OpenCV_LIBS opencv_core opencv_imgproc opencv_highgui opencv_imgcodecs)

# linking

target_link_libraries(opencv_test ${OpenCV_LIBS})  ##改為自己的專案名稱
