Question

我是Cmake和Boost的新手。我现在正在使用cmake开发程序，需要帮助。

系统：Windows 7
Cmake版本：3.16.0-rc1
增强版：boost_1_71_0。通过.exe文件安装boost。
Gcc版本：4.8.1（rev5，由MinGW-W64项目构建）
Visual Studio：vs 2015

当我在cmake ..目录中运行build时，没有错误发生。输出为：

The C compiler identification is MSVC 19.0.24215.1
The CXX compiler identification is MSVC 19.0.24215.1

但是我想使用minGW进行编译，因此当我朗姆酒cmake -G "MinGW Makefiles"时，发生错误，提示“找不到Boost（缺少：Boost_INCLUDE_DIR）”。输出为：

The C compiler identification is GNU 4.8.1
The CXX compiler identification is GNU 4.8.1

运行cmake -G "MinGW Makefiles"时如何解决错误？谢谢大家！

Answer 1

我通过在set(BOOST_ROOT C:/local/boost_1_71_0)大声笑之前添加句子find_package(Boost REQUIRED)解决了这个问题... 但是我仍然想知道为什么我需要添加它。

Answer 2

您还可以在创建cmake项目（或CLion和其他IDE中的CMake选项）的过程中设置变量 BOOST_ROOT 。例如：

mkdir buildtest; cd buildtest
cmake -DBOOST_ROOT=/you_path_to_boost/boost ..
cmake --build . -- -j 4

Answer 3

我在Linux / Manjaro上也有类似的问题。确保已安装Boost，更具体地说是boost开发标头。我安装了boost运行时库，但没有标头。我安装了这些sudo pacman -S boost，它为我解决了这个问题。

Answer 4

我解决了这个问题之后，由于这里有了ToughMind，我遇到了以下问题：_Boost_COMPONENT_DEPENDENCIES和_Boost_MISSING_DEPENDENCIES。帮助我的是更新到最新的cmake版本，我从这里得到了答案：CMake finds Boost but the imported targets not available for Boost version

CMake错误：找不到Boost（丢失：Boost_INCLUDE_DIR）
