【问题描述】：

在 OSX 上，我已经使用 brew install boost 安装了 Boost，我正在尝试如下链接：

cmake_minimum_required(VERSION 3.13)
project(LinkBoost)

set(CMAKE_CXX_STANDARD 14)

add_executable(LinkBoost
    desmond.cpp
    desmond.h
    integration.cpp
    integration.h
    main.cpp
    main.h
    utillity.cpp
    utillity.h)

list(APPEND CMAKE_PREFIX_PATH "/usr/local/Cellar/boost/1.69.0_2")
set(Boost_ADDITIONAL_VERSIONS "1.69.0" "1.69")

find_package(BoostCOMPONENTS filesystem system test REQUIRED)

target_include_directories(LinkBoost PUBLIC ".")

# adds include directories, definitions and link libraries
target_link_libraries(VelocityDispersion PUBLIC
        Boost::filesystem Boost::system Boost::test)

然而这给了我：

Unable to find the requested Boost libraries.

Boost version: 1.69.0

Boost include path: /usr/local/Cellar/boost/1.69.0_2/include

Could not find the following Boost libraries:

      boost_test

Some (but not all) of the required Boost libraries were found.  You may
need to install these additional Boost libraries.  Alternatively, set
BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
to the location of Boost.

谁能帮我理解这里出了什么问题？我觉得我错过了一些明显的东西......

【问题讨论】：

Boost.Test 框架有几个不同的usage variants。您能否验证 Boost.Test 库是否已安装在您的系统上，可能与其他 libboost_ Boost 库一起安装，例如 libboost_system、libboost_filesystem 等。

【解决方案1】：

我已经设法让它与以下内容一起工作：

cmake_minimum_required(VERSION 3.13)
project(LinkBoost)

set(CMAKE_CXX_STANDARD 14)

FIND_PACKAGE(Boost COMPONENTS system filesystem unit_test_framework REQUIRED )
INCLUDE_DIRECTORIES( ${Boost_INCLUDE_DIR} )
LINK_DIRECTORIES ( ${Boost_LIBRARY_DIRS} )

add_executable(LinkBoost
    desmond.cpp
    desmond.h
    integration.cpp
    integration.h
    main.cpp
    main.h
    utillity.cpp
    utillity.h)

TARGET_LINK_LIBRARIES(LinkBoost LINK_PUBLIC
    ${Boost_LIBRARIES}
    ${Boost_FILESYSTEM_LIBRARY}
    ${Boost_SYSTEM_LIBRARY}
    ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})

但我认为问题的很大一部分在于我对 Boost 测试如何工作的基本理解 - 我鼓励任何在这里苦苦挣扎的人阅读 Boost 文档。
