您可以在 SET 命令中设置变量 CMAKE_SHARED_LINKER_FLAGS，加上 -Wl,-Bsymbolic 选项即可。修改后的 CMakeLists.txt 如下：

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(opencv_cl)

SET(OPENCV_PATH /home/toybrick/rk3588_opencv)

MESSAGE(STATUS "CMAKE_C_COMPILER:${CMAKE_C_COMPILER}")
MESSAGE(STATUS "CMAKE_CXX_COMPILER:${CMAKE_CXX_COMPILER}")
MESSAGE(STATUS "OPENCV_PATH:${OPENCV_PATH}")

INCLUDE_DIRECTORIES(${OPENCV_PATH}/include/opencv4 ${OPENCV_PATH}/include)
LINK_DIRECTORIES(${OPENCV_PATH}/lib /usr/lib/aarch64-linux-gnu/)

SET(LINK_LIBS opencv_world mali pthread dl)

SET(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} -Wl,-Bsymbolic")

ADD_EXECUTABLE(opencv_cl opencl_cs.cpp)

TARGET_LINK_LIBRARIES(opencv_cl ${LINK_LIBS})

这样设置 CMAKE_SHARED_LINKER_FLAGS 后，链接器在链接时会尽可能使用本地符号，而不是全局符号，从而解决符号版本不兼容的问题。
