使用cmake将仅标题库包含到我的项目时出错

我正在尝试将此仅标题库添加到我的项目中: https://github.com/CPPAlliance/url

CMakeLists.txt 在根文件夹中:

cmake_minimum_required(VERSION 3.18.0)

project(hftbot)
  
find_package(Boost 1.79.0 REQUIRED COMPONENTS system thread filesystem container)
find_package(Threads REQUIRED)
add_subdirectory(src)

include_directories(SYSTEM external/urlib/include)

set(URLIB_DIRECTORY "external/urlib/include")
set(URLIB_HEADERS ${URLIB_DIRECTORY}/boost/url.hpp ${URLIB_DIRECTORY}/boost/url/src.hpp)
set(SOURCES src/httpClient.cpp)

add_executable(${PROJECT_NAME} ${SOURCES} ${URLIB_HEADERS})
target_include_directories(${PROJECT_NAME} PRIVATE ${URLIB_DIRECTORY})

如你所见,我曾经 target_include_directories() 将头文件包含到我的项目中。 但这里似乎有点不对劲。

#include <boost/url.hpp>
#include <boost/url/src.hpp>

当我尝试包含这个时,它向我显示了构建错误:

我有一种感觉,是因为可执行文件的位置导致了这个错误吗?
