CMake找不到Boost libarary

我是新来的。我读过同样问题的帖子，但我仍然无法解决我的问题。对于同样的问题，我很抱歉

我的boost include位于：/usr/local/ceral/boost/1.58.0/include中 我的boost库位于：/usr/local/ceral/boost/1.58.0/lib中

我的CMakeLists.txt是：

cmake_minimum_required(VERSION 2.6)
SET(BOOST_ROOT /usr/local/Cellar/boost/1.58.0)
SET(BOOST_INCLUDEDIR /usr/local/Cellar/boost/1.58.0/include)
SET(BOOST_LIBRARYDIR /usr/local/Cellar/boost/1.58.0/lib)
set(Boost_USE_STATIC_LIBS   ON)
find_package(Boost COMPONENTS optional REQUIRED)

include_directories(${Boost_INCLUDEDIR})
target_link_libraries(hash ${Boost_LIBRARYDIR})

我得到的调试消息是：

CMake does not support this but it used to work accidentally and is being

我通过运行cmake来执行

编辑。问题已经解决了。正确的CMakeLists.txt应为：

cmake_minimum_required(VERSION 2.6)
SET(BOOST_ROOT /usr/local/Cellar/boost/1.58.0)
SET(BOOST_INCLUDEDIR /usr/local/Cellar/boost/1.58.0/include)
find_package(Boost REQUIRED)

include_directories(${BOOST_INCLUDEDIR})
add_executable(myProgram main.cc)

---

发生错误的原因是Boost.Optional是一个只包含头文件的文件，我不需要找到它的库

Boost.Optional是一个仅限头部的库：

看

find_包中的

组件

仅适用于内置库。所以，你只需要写：

find_package(Boost 1.58.0 REQUIRED)

---

请参阅类似链接：

好的，Boost。可选的是一个只包含标题的库，因此无法找到它的共享库，根据文档，该库的名称应该在

组件

参数中指定。我想这是问题的根源，您只需搜索boost本身，而不需要任何组件：

find_package(Boost REQUIRED)

---

在这种情况下，没有额外的预编译库，因此Boost不需要

target\u link\u库

。不需要可选（但项目中的其他第三方LIB可能需要可选）。

因此我将“find\u package（Boost COMPONENTS Optional required）”更改为“find\u package（Boost）”？我需要修改目标链接库吗？它现在不会给我错误消息，但我在使用“cmake”后找不到可执行文件。我按照您的建议更改了查找包并删除了目标链接库行。我还在行的末尾添加了“添加可执行文件（myProgram main.cc）”。我修改了查找包并用“target_link_libraries”。我还在文件末尾添加了“add_executable（myProgram main.cc）”。它没有显示任何错误，但我仍然找不到我的可执行文件。在执行

cmake..

后，运行

make

后，make仍然会告诉我“boost/optional.hpp”文件未找到。（你能打印变量

${boost\u INCLUDEDIR}

？使用：

消息（状态“include dir:${Boost\u INCLUDEDIR}”）

它是空的。它只打印“include dir:”。但是当我打开调试（即-DBoost\u debug=on）时，它会显示“Boost\u INCLUDEDIR=/usr/local/cillar/Boost/1.58.0/include”。为什么会这样？
