用户您好，请详细描述您所遇到的问题，这会帮助我们快速定位问题~

1.芯片型号：J5
2.天工开物开发包OpenExplorer版本：例如J5_OE_1.1.45等
3.问题定位：能否使用openmp并行开发
4.问题具体描述：cmakelist 添加openmp 报错 错误如下：

    你好，gcc9.3应该是自带支持openmp的，无需特殊配置，编译的时候加上-fopenmp参数看看，头文件使用#include

    cmake写法如下 ：

    if(OPENMP_FOUND)

    find_package(OpenMP REQUIRED)

    message("OPENMP FOUND")

    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")

    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")

    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")

    else()

    message("NOT OPENMP FOUND")

    endif()

    显示结果不支持 openmp：
