OpenCV运行有误

3253519642

使用的是ros一键安装自带的Opencv库，编写识别代码时使用

g++ `pkg-config opencv4 --cflags` 'test.cpp'  -o opencv3 `pkg-config opencv4 --libs`

可以正常编译运行，效果正常。
但是使用cmake后运行报错

[ WARN:0] global ./modules/videoio/src/cap_gstreamer.cpp (873) open OpenCV | GStreamer warning: Error opening bin: unexpected reference "test02" - ignoring
[ WARN:0] global ./modules/videoio/src/cap_gstreamer.cpp (616) isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created

以下是camke内容

cmake_minimum_required(VERSION 2.8)                            
PROJECT(test)                                         

FIND_PACKAGE( OpenCV REQUIRED )                              
INCLUDE_DIRECTORIES( ${OpenCV_INCLUDE_DIRS} )

ADD_EXECUTABLE(test test.cpp)
