为了检查库和测试编译，我写了一个简单的hello world程序。
如你所见，cmake有效，但当我使用make时，总会出现同样的错误：
文件无法识别!!! libopencv_videostab.so.2.4.8存在于该目录中。
这是CMakeLists.txt：
cmake_minimum_required(VERSION 2.8)
project( helloWorld )
find_package( OpenCV REQUIRED )
add_executable( helloWorld main.cpp )
target_link_libraries( helloWorld ${OpenCV_LIBS} )
这是toolchain.arm.cmake文件：
SET(CMAKE_C_COMPILER /usr/bin/arm-linux-gnueabi-gcc)
SET(CMAKE_CXX_COMPILER /usr/bin/arm-linux-gnueabi-g++)
SET(CMAKE_LINKER /usr/bin/arm-linux-gnueabi-ld)
SET(CMAKE_NM /usr/bin/arm-linux-gnueabi-nm)
SET(CMAKE_OBJCOPY /usr/bin/arm--gnueabi-objcopy)
SET(CMAKE_OBJDUMP /usr/bin/arm-linux-gnueabi-objdump)
SET(CMAKE_RANLIB /usr/bin/arm-linux-gnueabi-ranlib)
任何人都可以帮助我吗？我需要使用'OpenCV'库。
