Question

我想用CMake构建一个包含boost / beast库的Hello World项目。

main.cpp：

  1 #include <boost/beast.hpp>
  2 
  3 using namespace std;
  4 
  5 int main(){
  6     
  7     printf("hello, world!\n");
  8 
  9     return 0;
 10 }

在我的项目目录中，我做了：

git clone --recursive https://github.com/boostorg/boost.git

然后我创建了CMakeLists.txt文件：

cmake_minimum_required(VERSION 3.10)
project(beast_test_project)
add_executable(beast_test main.cpp)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/beast/include)

这在运行make时给我一个错误

fatal error: boost/core/exchange.hpp: No such file or directory
 #include <boost/core/exchange.hpp>

然后我添加了

#target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/mp11/include)

但是make给了我另一个相似。

因此，我一一添加了其他target_include_directories，直到摆脱了所有这些错误。这将导致我当前的CMakeLists.txt文件。

cmake_minimum_required(VERSION 3.10)
project(beast_test_project)

#include(${PROJET_SOURCE_DIR}/boost/libs/mp11/CMakeLists.txt)
#include(${PROJET_SOURCE_DIR}/boost/libs/asio/CMakeLists.txt)
#include(${PROJET_SOURCE_DIR}/boost/libs/core/CMakeLists.txt)
#include(${PROJET_SOURCE_DIR}/boost/libs/config/CMakeLists.txt)

add_executable(beast_test main.cpp)

#target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/beast/include)
#include(${PROJECT_SOURCE_DIR}/boost/libs/beast/CMakeLists.txt)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/beast/include)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/mp11/include)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/asio/include)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/core/include)
target_include_directories(beast_test PUBLIC ${PROJECT_SOURCE_DIR}/boost/libs/config/include)

我以这样的方式制作CMakeLists.txt文件，并假设Boost.Beast是仅标头的库（如github页上所述）。

如果任何人都可以为我指明如何编译此基础项目的正确方向，我将不胜感激。

使用CMake和Beast Library编译Hello World项目
