#include<iostream>

int main()
{
  #if defined __linux__
      std::cout<<"linux system"<<std::endl;
  #elif defined _WIN32
      std::cout<<"windows system"<<std::endl;
  #endif

#if defined  __aarch64__
      std::cout<<"this is arm cpu"<<std::endl;
  #elif defined __x86_64__
      std::cout<<"this id x86 cpu"<<std::endl;
  #endif
      return 0;
}

cmake 中判断CPU 架构，操作系统类型

cmake_minimum_required(VERSION 3.10.0)

message(${CMAKE_HOST_SYSTEM_NAME})
message(${CMAKE_HOST_SYSTEM_PROCESSOR})

if(CMAKE_HOST_SYSTEM_NAME MATCHES "Linux")
    message("this is Linux")
elseif(CMAKE_HOST_SYSTEM_NAME MATCHES "Windows")
  message("this is Windows")
endif()
if(CMAKE_HOST_SYSTEM_PROCESSOR MATCHES "aarch64")
    message("this is aarch64 cpu")
elseif(CMAKE_HOST_SYSTEM_PROCESSOR MATCHES "x86_64")
  message("this is x86_64 cpu")
endif()
