CLion + OpenCV 开发

CLion 按照正常的流程建立 Project 

而后修改CMakeLists.txt 

cmake_minimum_required(VERSION 3.8)
project(OpenCV_unit)
# CMake 会到变量 CMAKE_MODULE_PATH 指示的目录中查找文件 Findlibdb_cxx.cmake 并执行
find_package(OpenCV)
# 指定头文件的搜索路径，至关于指定gcc的-I参数 
include_directories(${OpenCV_INCLUDE_DIRS})

set(CMAKE_CXX_STANDARD 11)

set(SOURCE_FILES main.cpp)
add_executable(OpenCV_unit ${SOURCE_FILES})
# 添加连接库，相同于指定-l参数 
target_link_libraries(OpenCV_unit ${OpenCV_LIBS})
