我是根据上面的步骤安装编译Paddle的，在执行到第八步运行cmake时，生成了CMakeError.log。

错误信息如下所示：

Performing C SOURCE FILE Test CMAKE_HAVE_LIBC_PTHREAD failed with the following output:

Source file was:
#include <pthread.h>

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

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

return 0;
}

Determining if the function pthread_create exists in the pthreads failed with the following output:

请问pthreads库需要安装什么依赖？需要怎么处理这个错误异常才能顺利编译Paddle呢？
