Ubuntu使用cmake出现Performing Test CMAKE_HAVE_LIBC_PTHREAD

本文介绍: 解决 Pe r form in g Tes t CMAKE_HAVE_LIBC_PTHREAD – Fai led

因为我本身程序进展不顺利，我就以为这个上面有问题
在网上也搜索了很多解决办法，有的是因为我的下面的Found部分有的库没有Found成功而产生问题，添加库即可，但是我的并没有表明有缺失库，还有的说是cmake 指令后面需要添加-lpthread，我尝试过后并没有作用，当然，还有的说是cmake的版本问题，这里我查看了我的版本还比较新，于是没有进行更新尝试（也担心有更新失败的风向呐！！！）

然后我顺着cmake 相关文件查看了错误日志，日志内容

#include <pthread.h&gt;

void* test_func(void* data)
{
  return data;
}

int main(void)
{
  pthread_t thread;
  pthread_create(&amp;thread, NULL, test_func, NULL);
  pthread_detach(thread);
  pthread_join(thread, NULL);
  pthread_atfork(NULL, NULL, NULL);
  pthread_exit(NULL);

  return 0;
}
