opencv的CMakeLists.txt

cmake_minimum_required(VERSION 2.8)

project(my_run_name)

find_package(OpenCV REQUIRED)

add_executable(your_executable_file test_imgread.cpp)

target_link_libraries(videostab ${OpenCV_LIBS})

linux下使用opencv的cpp代码，对应的makefile

有imread.cpp和fun2.cpp,以及fun2.h三个文件

all: out

out: imread.o fun2.o

	g++ -o nice imread.o fun2.o `pkg-config --libs opencv`

imgread.o: imread.cpp

	g++ -c imread.cpp `pkg-config --cflags opencv`

fun2.o: fun2.cpp

	g++ -c fun2.cpp `pkg-config --cflags opencv`

如果是用CLion作为IDE，则其CMakeLists.txt写成：

cmake_minimum_required(VERSION 3.2)

project(opencv_test)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES main.cpp)

find_package(OpenCV REQUIRED)

add_executable(opencv_test ${SOURCE_FILES} source_file.h source_file.cpp)

target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBS})

也就是添加了倒数第1行和倒数第3行。
