打算在20.9下编译sunshine，但是cmake过不去。

查看CMakeErrorLog中显示：

Source file was:
#include

static void* test_func(void* data)

return data;
}

int main(void)

pthread_t thread;
pthread_create(&thread, NULL, test_func, NULL);
pthread_detach(thread);

return 0;

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

本地环境CMake是3.22，高于所需的3.18，网上也没查到解决办法。

路过的大神可否给点帮助？
