在mac中运行CGAL代码时出现编译错误

Question

我想在项目中使用CGAL。我用brew安装了CGAL：

brew install cgal

然后，我尝试运行一些简单的代码。我正在尝试运行此网页的第一个代码：

https://doc.cgal.org/4.7-beta1/Manual/introduction.html

我尝试使用以下命令编译代码：

g++ -lcgal points_and_segment.cpp -o points_and_segment

但是我收到了这个错误：

Undefined symbols for architecture x86_64:
  "boost::detail::get_tss_data(void const*)", referenced from:
      boost::thread_specific_ptr<double>::get() const in points_and_segment-78cb9a.o
  "boost::detail::set_tss_data(void const*, boost::shared_ptr<boost::detail::tss_cleanup_function>, void*, bool)", referenced from:
      boost::thread_specific_ptr<double>::reset(double*) in points_and_segment-78cb9a.o
      boost::thread_specific_ptr<double>::~thread_specific_ptr() in points_and_segment-78cb9a.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我试图在命令中包含-lboost或-lboost_thread。但后来我收到以下错误：

ld: library not found for -lboost
clang: error: linker command failed with exit code 1 (use -v to see invocation)

ld: library not found for -lboost_thread
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我用-v尝试了同样的方法。然后我得到以下内容：

我找了cgal安装文件夹。它是我机器中的以下路径：

cd /usr/local/opt/cgal/

boost的文件夹是：

cd /usr/local/opt/boost/
.brew/                INSTALL_RECEIPT.json  include/              lib/
