Question

我正在一个需要libzmq的大项目中，并且猜测应该在Windows.h中处理一些宏。

以下是测试代码：

cmake_minimum_required(VERSION 2.8.12)

project(qt_compiler_error)

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)

include_directories(C:/code/libzmq/include)
link_directories(C:/code/libzmq/lib)

find_package(Qt5Core)

add_executable(${PROJECT_NAME} "main.cpp")

target_link_libraries(${PROJECT_NAME} Qt5::Core)
target_link_libraries(${PROJECT_NAME} libzmq-v141-mt-4_3_0)

main.cpp：

#include <QCoreApplication>

#include <zmq.hpp>
#include <Windows.h>
#undef near
#undef far

#include <iostream>

int main(int argc, char *argv[]) {
  QCoreApplication a(argc, argv);

  std::cout << "hello\n";
  // sleep(1);
  return a.exec();
}

这样，代码可以很好地编译。但是，如果将#include <zmq.hpp>移动到#undef far之后的行，则会在编译中发生很多错误：

因此Windows.h中必须有某些内容。我想在需要的任何地方导入zmq.hpp怎么办>

如何使用windows.h解决libzmq冲突
