我刚刚通过brew安装了ZMQ库，我可以看到/usr/local/include和/usr/local/bin中的文件，但当我将这些路径添加到XCode中的Header Search Path和library Search Path时，我无法使用#include，因为它继续告诉我找不到文件。
即使我将/usr/local/Cellar/zeromq/4.1.4/include（安装实际库的位置）添加到Header Search Path，它仍然找不到zmq.h，即使文件存在于其中。
我该怎么办？
编辑：
完整的来源只是来自ZMQ themselfe，的一个示例文件
//
// Hello World client in C++
// Connects REQ socket to tcp://localhost:5555
// Sends "Hello" to server, expects "World" back
//
#include <zmq.h>
#include <string>
#include <iostream>
int main ()
{
// Prepare our context and socket
zmq::context_t context (1);
zmq::socket_t socket (context, ZMQ_REQ);
std::cout << "Connecting to hello world server…" << std::endl;
socket.connect ("tcp://localhost:5555");
// Do 10 requests, waiting each time for a response
for (int request_nbr = 0; request_nbr != 10; request_nbr++) {
zmq::message_t request (5);
memcpy (request.data (), "Hello", 5);
std::cout << "Sending Hello " << request_nbr << "…" << std::endl;
socket.send (request);
// Get the reply.
zmq::message_t reply;
socket.recv (&reply);
std::cout << "Received World " << request_nbr << std::endl;
}
return 0;
}
确切的错误只是"词法或预处理器问题，找不到'zmq.h'文件main.cpp"

我不知道发生了什么，但我只是重新创建了整个项目，做了与以前完全相同的步骤，现在它像应该的那样编译和运行。
我使用的项目是不久前的，所以可能是其他原因导致了问题。
