CLion 和 Boost 1.60.0

Question

在过去的几天里，我一直在努力将 Boost 库包含在我的项目中。我一直在阅读和使用 Stack Overflow 上众多海报提出的建议，出于某种我不明白的原因，我仍然无法让 CMake 找到 Boost，或者如果它确实找到了 Boost，我无法编译，因为它不能找到我显然需要链接的 boost_system 库以删除系统 config() not found 错误。

我目前正在使用 GNU C++ 编译器 v4.9.3-1 的 MinGW 实现在 Windows 10 上工作

目前在我的系统上提取了 Boost：

C:\boost_1_60_0

这是我的 CMake 文件当前的样子：

cmake_minimum_required(VERSION 3.5)
project(Engine)

#SET(GCC_COVERAGE_LINK_FLAGS "-lboost_system")

message(STATUS "start running cmake...")

SET(BOOSTROOT "C:/boost_1_60_0/")
SET(BOOST_ROOT "C:/boost_1_60_0/")
SET(BOOST_LIBRARYDIR "C:/boost_1_60_0/libs/")

find_package(Boost 1.60.0 COMPONENTS system REQUIRED)

if(Boost_FOUND)

    message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
    message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARIES}")
    message(STATUS "Boost_VERSION: ${Boost_VERSION}")

    include_directories(${Boost_INCLUDE_DIRS})
    add_definitions("-DHAS_BOOST")

endif()

add_executable(Engine main.cpp)

if(Boost_FOUND)

    target_link_libraries(Engine ${Boost_LIBRARIES})

endif()

set(SOURCE_FILES main.cpp)

我目前遇到的错误是：

Error:Unable to find the requested Boost libraries.
Boost version: 1.60.0
Boost include path: C:/boost_1_60_0
Could not find the following Boost libraries:
        boost_system
No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to the location of Boost.

** 更新 ** 这是使用 -DBoost_Debug=ON 运行 cmake 时的输出：

_boost_TEST_VERSIONS = 1.61.0;1.61;1.60.0;1.60
Boost_USE_MULTITHREADED = TRUE
Boost_USE_STATIC_LIBS =

有一些有用的标志可以帮助 FindBoost 查找库。

在调用 find_package(Boost) 之前尝试设置这些变量（打开或关闭 - 这取决于您的 boost 安装）

set(Boost_LIB_PREFIX            "lib"       CACHE STRING "")
set(Boost_USE_MULTITHREADED     ON          CACHE BOOL "") # '-mt' flag
set(Boost_USE_STATIC_LIBS       ON          CACHE BOOL "")
set(Boost_USE_STATIC_RUNTIME    ON          CACHE BOOL "") # '-s' tag
set(Boost_USE_DEBUG_RUNTIME     ON          CACHE BOOL "") # '-g' tag
set(Boost_COMPILER              "-mgw49"    CACHE STRING "")

使用set(Boost_DETAILED_FAILURE_MSG TRUE) 设置标志将极大地帮助您进行诊断
