DLDR如何将 cmake 指向 boost-python3 库？ cmake 不会自动检测到它。
我正在尝试建立caffe https://github.com/BVLC/caffe对于 Python 3.6，使用提供的 cmake。
我的系统规格：
- Python 3.6.5，Anaconda 自定义（64 位）
- Mac 操作系统 10.13.6
- No CUDA
我已经用brew安装了boost，例如
brew install boost boost-python3
我可以使用以下命令查看 boost 库find / -name libboost* 2>/dev/null。它们出现在三个目录中
-
/usr/local/Cellar/boost/1.67.0_1/lib/
-
/usr/local/lib/-> 上面的符号链接
- boost-python3 位于
/usr/local/Cellar/boost-python/1.67.0/lib/
如果我跑cmake -DCMAKE_PREFIX_PATH=<anaconda_env_path> -D python_version=3，我在输出的顶部得到了这个
-- Boost version: 1.67.0
-- Found the following Boost libraries:
-- system
-- thread
-- filesystem
-- chrono
-- date_time
-- atomic
但更进一步，我还得到

如同Cmake 找不到 Boost https://stackoverflow.com/questions/3808775/cmake-doesnt-find-boost，我尝试添加
-DBOOST_ROOT=/usr/local/Cellar/boost/1.67.0_1/lib/ -DBoost_DEBUG=1
到 cmake 命令。在生成的输出中，以下内容对 boost_python-py365、boost_python-py36、boost_python-py3 和 boost_python 重复 3 次：

Could NOT find Boost
Boost version: 1.67.0
Boost include path: /usr/local/Cellar/boost/1.67.0_1/include
Could not find the following Boost libraries:
boost_python
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.
因此，我认为 boost-python 路径是缺失的。我也尝试添加-DBOOST_LIBRARYDIR，但这似乎并没有改变任何事情。
The FindBoost 文档 https://cmake.org/cmake/help/latest/module/FindBoost.html包含有关 boost-python 的评论
请注意，Boost Python 组件需要 Python 版本后缀
（Boost 1.67 及更高版本），例如python36 或 python27 版本
分别针对 Python 3.6 和 2.7 构建。这也适用于
使用 Python 的其他组件，包括 mpi_python 和 numpy。
早期的 Boost 版本可能使用特定于发行版的后缀，例如
2、3 或 2.7。这些也可以用作后缀，但请注意它们
不便于携带。
我注意到 boost-python3 库的后缀为 37 (libboost_python37.a)，因此我也尝试使用带有 python 3.7 的 anaconda 环境，但同样的错误仍然存在。
如何让我的 cmake 找到 boost-python3 库？
