Setting up cpp-httplib with Cmake For Building REST API

Setting up cpp-httplib with Cmake For Building REST API

In this blog I'll be using cpp-http lib, a header only ( single file ) c++ server & client.

I'll be using it with Cmake to run an http server.

Here is the link to the project on github. Click here

I'll start by creating a directory for the project.

$ mkdir api

Next I'll create the Files I need :

$ touch CMakeLists.txt httplib.h main.cpp 

Creating the build directory

$ mkdir build 

CMakeLists.txt

cmake_minimum_required(VERSION 3.15)
project(api)
add_executable(api main.cpp)
target_include_directories(
    api
    PRIVATE
    ${cmake_current_dir}
    )

main.cpp

#include "httplib.h"

int main(void)
{
  using namespace httplib;

  Server svr;

  svr.Get("/", [](const Request& req, Response& res) {
    res.set_content("Hello World!", "text/plain");
  });


  svr.listen("localhost", 8080);
}

Build Steps :

$ cd build
$ cmake ..
$ make
