重新加载 cmake 项目时出错-“找不到 Boost”答案

【问题标题】：Error reloading cmake project-"Could NOT find Boost"重新加载 cmake 项目时出错-“找不到 Boost”
【发布时间】：2021-09-04 22:30:28
【问题描述】：

我是 Cmake 和 boost 的新手。我现在正在开发一个开源程序，并想重新加载 cmake 项目。

我已经用brew（MacOS）安装了boost 1.74.0，我检查了目录“/usr/local/Cellar/boost/1.74.0”，找到了lib目录“/usr/local/Cellar/boost /1.74.0/lib" 具有预期的 .a 和 .dylib 文件。以下是lib目录中的部分文件：

-r--r--r--   1 lulijun  staff   9550840  8 11  2020 libboost_regex-mt.a
-r--r--r--   1 lulijun  staff   1004840  6 21 11:20 libboost_regex-mt.dylib
-r--r--r--   1 lulijun  staff   9550840  8 11  2020 libboost_regex.a
-r--r--r--   1 lulijun  staff   1004648  6 21 11:20 libboost_regex.dylib

但是当我尝试重新加载 cmake 项目时，出现以下问题

-- Could NOT find Boost: missing: thread regex system filesystem date_time program_options (found /usr/local/lib/cmake/Boost-1.74.0/BoostConfig.cmake (found suitable version "1.74.0", minimum required is "1.74.0"))



  CMake Error at src/service/CMakeLists.txt:32 (add_executable):
  Target "palo_be" links to target "Boost::regex" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

这是我在 cmake 文件中的 boost 配置：

# Set Boost
set(Boost_DEBUG FALSE)
set(Boost_USE_MULTITHREADED ON)
set(BOOST_ROOT /usr/local/Cellar/boost/1.74.0)
set(Boost_NO_SYSTEM_PATHS ON)
set(Boost_NO_BOOST_CMAKE OFF)

SET(Boost_INCLUDE_DIR /usr/local/Cellar/boost)


find_package(Boost 1.74.0 COMPONENTS thread regex system filesystem date_time program_options)

我有什么遗漏吗？我该如何解决这个问题？

这是 Boost_DEUBUG = TRUE 的完整消息，有太多 CMake 错误但它们看起来一样，所以我只复制其中的 2 个。

【问题讨论】：

请将 Boost_DEBUG 设置为 TRUE 并重新运行 CMake。这应该可以让您更好地了解发生了什么。
请粘贴完整的 CMake 输出消息。
@Botje 谢谢，我将 Boost_DEBUG 设置为 TRUE，发现它确实扫描了 lib 目录并找到了一些关于线程和正则表达式等的文件，但下一步是“找不到 Boost”错误仍然出现。完整的消息太长，所以我把它粘贴在问题的正文中
@prehistoricpenguin 感谢您抽出宝贵时间，完整的消息太长，所以我将其粘贴在问题的正文中。
好像是链接部分的问题，不是你粘贴的find_package部分，尝试用链接中的boost_thread替换

标签： c++ boost

【解决方案1】：

最后的评论揭示了您的问题：您（或您的系统）选择了 Boost 的标志组合，导致无法找到正确的库：

Boost_USE_STATIC_LIBS: 只选择要包含在程序中的 .a 文件
Boost_USE_STATIC_RUNTIME：只选择“静态链接到 C++ 运行时”的文件。它们的变体中有一个“s”标签，但在您的系统上不存在。

至少关闭Boost_USE_STATIC_RUNTIME，然后由你决定是否要与Boost动态链接。
