为什么不能cmake findBoost查找系统升压路径？

Question

我试图让我的项目cmake句柄依赖关系， 但似乎cmake无法找到提升我的系统。

cmake_minimum_required(VERSION 3.8) 
project(QuineMccluskeyExample) 

set(CMAKE_CXX_STANDARD 14) 

if(MSVC) 
    set(CMAKE_CXX_FLAGS "/WX- /Wall /O2 /Ob2") 
else() 
    set(CMAKE_CXX_FLAGS "-pthread -Wall -O3") 
endif() 

# header only library 
add_library(QuineMccluskey INTERFACE) 
target_include_directories(QuineMccluskey INTERFACE include/) 

# example project source directories 
set(EXAMPLES ${PROJECT_SOURCE_DIR}/examples) 

set(SOURCE_FILES 
    ${EXAMPLES}/main.cpp) 


# Boost dependency 
find_package(Boost 1.63.0 COMPONENTS REQUIRED 
    dynamic_bitset 
    config 
    core 
    move 
    static_assert 
    assert 
    exception 
    integer) 

if(Boost_FOUND) 
    message("found BOOST: " ${BOOST_ROOT}) 
    include_directories(${Boost_INCLUDE_DIR}) 
    add_executable(QuineMccluskeyExample ${SOURCE_FILES}) 
else() 
    message("couldn't find boost") 
endif() 

这是我的CMakeLists.txt文件 及以下cmake的输出日志

Boost version: 1.64.0 

    Boost include path: /usr/include 

    Could not find the following Boost libraries: 

      boost_dynamic_bitset 
      boost_config 
      boost_core 
      boost_move 
      boost_static_assert 
      boost_assert 
      boost_integer 

    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. 

以上就是让findBoost找我的系统路径的结果。 我的系统路径是/ usr/include/boost cmake说它找到的路径是正确的。 我检查了所有需要的依赖项标题， 但由于某种原因，cmake无法找到它们。

手动提供-DBOOST_ROOT =“/ usr/include”取得了相同的结果。

低于

是/ usr/include中/升压

提升是对的archlinux回购

还有一个问题的最新分布1.64_02。 有没有一种干净的方式来包括对git CMake项目的提升依赖关系？ 就像使用子模块一样？ 我试过，但不能出来一个简单的干净的想法。

手动提供-DBOOST_ROOT = “/ usr/include目录”

你提供了错误的位置。相反，你应该做

-D BOOST_LIBRARYDIR=/usr/lib/boost 

或无论你的Boost库在哪里。
