编译程序用到opencv库，链接时候出错

编译应用程序的时候，链接opencv库的时候总是报错，相关库是有的，路径也是对的，不知道为什么，

cmakelist中的部分设置

link_directories("/home/zng/zng/X1000V5.0/out/product/rat/system/lib/"
"/home/zng/zng/app/mips-opencv/lib"
"/home/zng/zng/X1000V5.0/out/product/rat/system/usr/lib/"
"/home/zng/zng/app/mips-opencv/3rdparty/lib/"
"/home/zng/zng/app/freetype/")

link_libraries("dl" "pthread" "opencv_imgproc" "opencv_highgui" "opencv_core" "zlib" "libjasper" "libjpeg" "libpng" "IlmImf" "libtiff" "rt" "z" "freetype")

这些库在对应的路径下都是有的，求教各位大神。
