cmake中配置支持openMP并行


mlpack was compiled with OpenMP support, but you are compiling without OpenMP support


option(USE_OPENMP "If available, use OpenMP for parallelization." ON)
if (USE_OPENMP)
  find_package(OpenMP)
endif ()
if (OPENMP_FOUND)
  add_definitions(-DHAS_OPENMP)
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
endif ()
