OpenCV 3 的"ld: symbol(s) not found for architecture x86_64"

我已经在mac Yosemite上使用CMAKE安装了OPENCV 3。我正在使用Eclipse IDE，在构建解决方案时显示错误:

g++ -L/usr/local/lib -o "test1"  ./main.o   -lopencv_imgcodecs -lopencv_highgui -lopencv_core
Undefined symbols for architecture x86_64:

      _main in main.o

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [test1] Error 1

我在设置中添加了头文件和库。请帮我去掉这个错误。提前感谢
