问题描述#include <boost/format.hpp>失败

在复现slam十四讲第五讲的代码，运行建立点云图的代码时，调用boost库的时候总是失败

CMakeLists.txt

<code>cmake_minimum_required(VERSION 3.17)
find_package(Sophus REQUIRED)
include_directories(${Sophus_INCLUDE_DIRS})

find_package(Pangolin REQUIRED)

find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIR})

add_executable(joinMap joinMap.cpp)
# 为什么在这要用Sophus::Sophus 为什么有的是_LIBS 有的是LIBRARIES
target_link_libraries(joinMap ${OpenCV_LIBS} ${Pangolin_LIBRARIES} ${Boost_LIBRARIES})
target_link_libraries(joinMap Sophus::Sophus)
</code>

错误：Could NOT find Boost (missing: Boost_INCLUDE_DIR)

<code>/Applications/CLion.app/Contents/bin/cmake/mac/bin/cmake -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - Unix Makefiles" /Users/leohao/Documents/YBU/Slam/ch5

</code>

解决方案

<code>set(BOOST_ROOT  /Users/leohao/Documents/lib/boost_1_74_0)
</code>

将这句写在find_package(Boost REQUIRED)前

问题原因

CMake版本太旧。CMake无法检测到不同Boost库之间的依赖关系。可能更新CMake，它也将正常工作。
