CMake发现Boost但没有请求库

我正在尝试使用CMake将Boost添加到C ++应用程序中。我已经阅读了所有可以在SO上找到的相关问题，我觉得我越来越接近解决方案了。但由于某些原因，CMake仍无法找到所请求的Boost库。

我正在尝试找到“boost_filesystem”。调试显示CMake正在寻找“boost_filesystem-vc141-mt-gd-1_65_1”。我的文件夹“C：\ boost \ boost_1_65_1 \ stage \ lib”中有“libboost_filesystem-vc141-mt-gd-1_65_1.lib”文件。我想这是CMake正在寻找的文件，但由于某些原因，CMake说它无法找到它。

这是我用来构建Boost的过程。对于大多数人来说这可能是太多的细节，但我怀疑它可能对另一个新手有帮助。

  1. 在文件夹C：\ boost \ boost_1_65_1
    2. 中下载并解压缩Boost 1.65.1
  2. 转到开发人员提示命令行并在上面的文件夹下运行bootstrap.bat。
  3. 在C：\ boost \ boost_1_65_1 \ boost \ config \ compiler下更新了visualc.hpp文件（参见Unknown compiler version while compiling Boost with MSVC 14.0 (VS 2015)！

    4. 替换了visualc.hpp文件底部的行：

    // last known and checked version is 19.11.25506 (VC++ 2017.3):
#if (_MSC_VER > 1911)

    带

    // last known and checked version is 19.13.26128 (VC++ 2017.5.6):
#if (_MSC_VER > 1913)

    1. 在文件夹boost_1_65_1下打开另一个文件project-config.jam，并将第二行更新为以下内容：

      使用msvc：14.1：“C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Professional \ VC \ Tools \ MSVC \ 14.13.26128 \ bin \ Hostx64 \ x64 \ cl.exe“;

    2. 返回开发人员提示命令行并运行以下命令来构建Boost：

      b2 toolset = msvc-14.1 address-model = 64

      3. 我似乎已正确完成以下项目：

      • 正确构建了库，但未使用默认目录。我确认建立了所请求的库。
      • 将路径正确分配给CMake指定目录
      • 正确使用了CMake find_package（）

      以下是我使用的相关版本：

      • VS：2017 v15.6.1 with CMake 3.10
      • Boost版本：1.65.1，使用工具MSVC 14.1构建

      这是CMakelist.txt：

      cmake_minimum_required(VERSION 3.6 FATAL_ERROR)
project(test)

set(Boost_USE_STATIC_LIBS       OFF)
set(Boost_USE_MULTITHREADED      ON)
set(Boost_USE_STATIC_RUNTIME    OFF)

set(Boost_DEBUG ON)

set(BOOST_ROOT C:\\boost\\boost_1_65_1)
set(BOOST_INCLUDEDIR C:\\boost\\boost_1_65_1)
set(BOOST_LIBRARYDIR C:\\boost\\boost_1_65_1\\stage\\lib)

set(Boost_DEBUG 1)

find_package(Boost COMPONENTS filesystem REQUIRED)

message(STATUS "Boost LIBRARIES: " ${Boost_LIBRARIES})   
add_executable(test_Boost main.cpp)
target_link_libraries(test_Boost ${Boost_LIBRARIES})

      这是可能相关的输出的一部分：

答案 0 :(得分：1)

libboost_filesystem-vc141-mt-gd-1_65_1.lib是文件系统库的静态版本（名称以 lib 开头）

在CMake中，您正在搜索动态版本：

set(Boost_USE_STATIC_LIBS       OFF)

这不起作用。现在你必须选择：

  1. 将OFF切换为ON
  2. 通过以下添加重建boost：

    3. b2 toolset=msvc-14.1 address-model=64 --build-type=complete

    命令--build-type=complete构建所有支持的库变体。只是为了安全起见; - ）
