c++ - cmake 找到库但未包含在生成的 makefile 中

Question

我正在尝试使用 CMake 编译一个使用 boost 的多文件 C++ 项目。我的 CMakeLists.txt 文件如下所示:

cmake_minimum_required(VERSION 2.8)
set(Boost_USE_STATIC_LIBS        ON) # only find static libs
set(Boost_USE_MULTITHREADED      ON)
set(Boost_USE_STATIC_RUNTIME    OFF)
find_package(Boost 1.53.0 COMPONENTS serialization)
if(Boost_FOUND)
  include_directories(${Boost_INCLUDE_DIRS})
  add_executable(RandomFor RandomFor.cpp)
  target_link_libraries(RandomFor ${Boost_LIBRARIES})
endif()

当我运行 cmake .. 我得到以下输出

CMake ..

好像是找到序列化库了。当我运行 make 时，我在尝试构建时遇到错误，表明它找不到 serialization.hpp:

其中似乎没有提及 Boost。关于为什么生成的 Makefile 不起作用的任何帮助？

Answer 1

根据您尝试编译的编译器(可能还有操作系统)，您不得在包含指令中使用反斜杠。

尝试像这样包含:

#include <boost/serialization/serialization.hpp>
