opencv3.2交叉编译遇到上述无法找到问题，本项目中OpenCV中使用的是生成的静态库。

编译方法，

是在cmake的时候

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_SHARED_LIBS=OFF -D BUILD_SHARED_LIBS=NO -D BUILD_PNG=ON -D BUILD_JASPER=ON -D BUILD_JPEG=ON -D BUILD_TIFF=ON -D BUILD_ZLIB=ON -D WITH_JPEG=ON -D WITH_PNG=ON -D WITH_JASPER=ON -D WITH_TIFF=ON ..

将build-shared-libs 关掉，在cmake-gui中将勾去掉。

生成的目录其中lib里边都是opencv的静态库，share里边有第三方的libjpeg的库

lid@lid-VirtualBox:~/build-opencv3/insatll$ ls
bin  include   lib  LICENSE  share
lid@lid-VirtualBox:~/build-opencv3/insatll$ ls lib/
a                    libopencv_core.a        libopencv_flann.a    libopencv_imgcodecs.a  libopencv_ml.a         libopencv_photo.a  libopencv_stitching.a  libopencv_video.a    libopencv_videostab.a
libopencv_calib3d.a  libopencv_features2d.a  libopencv_highgui.a  libopencv_imgproc.a    libopencv_objdetect.a  libopencv_shape.a  libopencv_superres.a   libopencv_videoio.a  so
lid@lid-VirtualBox:~/build-opencv3/insatll$ ls share/OpenCV/3rdparty/lib/
libIlmImf.a  liblibjasper.a  liblibjpeg.a  liblibpng.a  liblibtiff.a  liblibwebp.a  libzlib.a
lid@lid-VirtualBox:~/build-opencv3/insatll$ 

我们将这些库拷贝到Makefile下的编译环境下。

其中Makefile的顺序一定要注意。

objdetect depends upon imgproc。

这样写是不会出问题的。
