C++ CMake在Windows上的自定义位置上找不到Boost

我已经下载并构建了文档中描述的Boost。 现在我想通过CMake将一个示例程序链接到该版本的Boost

这是我当前的文件夹结构：

cmake-boost
    - boost_1_73_0/ (Boost folder)
    - build/
    - CMakeLists.txt
    - cmake-boost.cpp

这是我的

CMakeLists.txt

文件的内容：

cmake_minimum_required(VERSION 3.5 FATAL_ERROR)

project(cmake-boost LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_EXTENSIONS OFF)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(BOOST_ROOT "boost_1_73_0")
set(BOOST_LIBRARYDIR "boost_1_73_0/stage/lib")

find_package(Boost REQUIRED COMPONENTS regex)

if(Boost_FOUND)
    message(STATUS "Success!")
endif()

add_executable(cmake-boost cmake-boost.cpp)

target_link_libraries(cmake-boost
    PUBLIC
        Boost::regex
)

如果我从

build

文件夹中运行

cmake..

，我只会收到以下消息，说明它找不到请求的库

我注意到有两件事可能是错误的：

这一行

-[C:/ProgramFiles/CMake/share/CMake-3.14/Modules/FindBoost.CMake:1484]猜测了(boost)编译器=-vc141-vc140

但是如果我看一下boost构建期间生成的

.lib

文件，它们的名称中有

-vc142

似乎cmake正在搜索正确的文件夹，但使用了错误的库文件名。它使用的名称是

boost_regex-vc141-mt-x64-1_73

，但我的boost build startet中的

lib

文件类似于

libboost_regex-vc142-mt-x64-1_73.lib

我通过在

cmake

命令中添加

-DBoost\u COMPILER=-v142

解决了第一个问题。但是我不能用

-DBoost\u LIB\u PREFIX=LIB设置
Boost\u LIB\u前缀
，我找到了一个解决方案。
正如我上次编辑问题时提到的，编译器的第一个问题可以通过
-DBoost\u compiler=-vc142
选项解决。
第二个问题可以通过使用
-DBoost\u USE\u STATIC\u LIBS=ON
来解决

因此，boost的
CMakeLists
中的
set
块现在是：

set(BOOST_ROOT "boost_1_73_0")
set(Boost_COMPILER "-vc142")
set(Boost_USE_STATIC_LIBS ON)

设置了这些变量后，CMake运行不会出现任何问题。
这是否回答了您的问题@MarekR没错，我的坏蛋根据日志中的路径
C:/Users/djc3ho/Documents/Programming/cpp/\u Testing/cmake\u boost/boost\u 1\u 73\u 0
，cmake已经能够在您的位置找到boost至少部分。问题是CMake无法在您所在的位置找到
boost\u regex
库。要调试此问题，请使用附加选项
-DBoost\u debug=ON
运行
cmake
。使用此选项，CMake将输出选中的精确文件。将它们与安装中实际拥有的进行比较。另请注意，新的Boost版本可能有不正确的…

-这可能是您问题的核心。@MarekR我曾将上述问题作为我问题的基础，但它没有解决问题。我也尝试了完整路径，但在CMake 3.14

-vc141

和

-vc140

中也不起作用编译器后缀以使用而闻名。例如，在CMake 3.17.3中，了解后缀的完整范围，

-vc149

，

-vc148

<代码>-vc140。因此，警告

新的Boost版本

实际上与您的问题有关：较新版本的CMake不需要设置

Boost\u编译器

变量。（这绝非有意贬低你的调查和答案）。
