【问题描述】：
我使用自制软件在 MacOS High Sierra 10.13.3 上安装了 Boost 1.60：brew install boost@1.60
我正在运行 CLion 2018.1.1，我的工具链设置如下：捆绑 CMake 3.10.3、C++ 编译器 /Library/Developer/CommandLineTools/usr/bin/c++、GNU Make 3.81
我的CMakeLists.txt文件如下：
cmake_minimum_required(VERSION 3.10)
project(xxx)
set(CMAKE_CXX_STANDARD 17)
add_executable(${PROJECT_NAME} main.cpp)
Set(BOOST_ROOT /usr/local/Cellar/boost@1.60/1.60.0)
find_package(Boost 1.60.0 REQUIRED COMPONENTS system filesystem regex)
if(Boost_FOUND)
message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARIES}")
message(STATUS "Boost_VERSION: ${Boost_VERSION}")
include_directories(${BOOST_ROOT})
include_directories(${Boost_INCLUDE_DIRS})
link_directories(${Boost_LIBRARY_DIRS})
target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES})
endif()
构建似乎成功了：
-- Boost version: 1.60.0
-- Found the following Boost libraries:
-- system
-- filesystem
-- regex
-- Boost_INCLUDE_DIRS: /usr/local/Cellar/boost@1.60/1.60.0/include
-- Boost_LIBRARIES: /usr/local/Cellar/boost@1.60/1.60.0/lib/libboost_system-mt.dylib;/usr/local/Cellar/boost@1.60/1.60.0/lib/libboost_filesystem-mt.dylib;/usr/local/Cellar/boost@1.60/1.60.0/lib/libboost_regex-mt.dylib
-- Boost_VERSION: 106000
但我在尝试执行时收到以下链接器错误：
架构 x86_64 的未定义符号： “boost::re_detail_106000::perl_matcher, std::__1::allocator >>, boost::regex_traits >>::construct_init(boost::basic_regex >> const&, boost::regex_constants::_match_flags)”，引用自： boost::re_detail_106000::perl_matcher, std::__1::allocator >>, boost::regex_traits >>::perl_matcher(std::__1::__wrap_iter, std::__1::__wrap_iter, boost::match_results, std ::__1::allocator > > >&, boost::basic_regex > > const&, boost::regex_constants::_match_flags, std::__1::__wrap_iter) 在 main.cpp.o “boost::re_detail_106000::perl_matcher, std::__1::allocator > >, boost::regex_traits > >::match()”，引用自： bool boost::regex_match, std::__1::allocator > >, char, boost::regex_traits > >(std::__1::__wrap_iter, std::__1::__wrap_iter, boost::match_results, std::__1 ::allocator > > >&, boost::basic_regex > > const&, boost::regex_constants::_match_flags) 在 main.cpp.o ld：未找到架构 x86_64 的符号
我做错了什么，我该如何解决？

运行
make VERBOSE=1并发布链接行。这将显示您尝试链接的实际库。 -
