Cmake不适用于Maverick上的openMP

我使用OpenMP编写并行代码.以下是我案例中使用的CMakeLists的一部分.

FIND_PACKAGE( OpenMP REQUIRED)
    if(OPENMP_FOUND)
    message("OPENMP FOUND")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
    endif()

但是,当我们启动cmake ..时,似乎它没有找到OpenMP包,我得到了这个错误

CMake Error at /opt/local/share/cmake-3.3/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find OpenMP (missing: OpenMP_C_FLAGS OpenMP_CXX_FLAGS)

这是CMakeLists.txt

cmake_minimum_required(VERSION 2.6)

#Declaration du projet

endif()

)

target_link_libraries(

)

我该如何解决这个问题？我确信openMPi已安装且位于opt/local/include上
