Ubuntu 下找不到Pthread库的方法

  2 find_package(Threads REQUIRED)
  3 if(THREADS_HAVE_PTHREAD_ARG)
  4   set_property(TARGET fork  PROPERTY COMPILE_OPTIONS "-pthread")
  5     set_property(TARGET fork  PROPERTY INTERFACE_COMPILE_OPTIONS "-pthread")
  6     endif()
  7     if(CMAKE_THREAD_LIBS_INIT)
  8       target_link_libraries(fork  "${CMAKE_THREAD_LIBS_INIT}")
  9       endif()

　在对应的CMakeLists.txt文件夹下添加以上内容
