c++ - 如何为 CMake 指定仅限标头的 boost 库？

Question

我正在使用以下 cmake 文件

cmake_minimum_required(VERSION 3.16)
project(Translated01)

find_package(Boost REQUIRED)
find_package(OpenSSL REQUIRED)

set(CMAKE_CXX_STANDARD 14)

add_executable(Translated01 main.cpp)

在 CMake 配置阶段它写

...
[cmake] -- Check for working CXX compiler: /usr/bin/g++-7 - skipped
[cmake] -- Detecting CXX compile features
[cmake] -- Detecting CXX compile features - done
[cmake] -- Found Boost: /opt/boost (found version "1.73.0")  
[cmake] -- Found OpenSSL: /usr/lib/x86_64-linux-gnu/libcrypto.so (found version "1.1.1")  
[cmake] -- Configuring done
[cmake] -- Generating done

这证明它boost在/opt/boost.

不幸的是，在编译期间它说它找不到包含文件

[build] ../main.cpp:3:10: fatal error: boost/beast.hpp: No such file or directory
[build]  #include <boost/beast.hpp>
[build]           ^~~~~~~~~~~~~~~~~
[build] compilation terminated.

虽然，文件在那里

$ ls /opt/boost/boost/beast.hpp
/opt/boost/boost/beast.hpp

boost那么，如何CMake正确配置呢？
