c++ - cmake 找不到 boost linux

Question

我正在尝试使用来自 Boost 的 program_options 库。但是，CMake 可以也不能找到 boost ...我做错了什么？

CMakeLists.txt:

cmake_minimum_required (VERSION 3.8)
project(myProject)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_FLAGS "-std=c++0x -g -Wall -O3")

set(CMAKE_CXX_FLAGS_DEBUG "-g")

include_directories ("${PROJECT_BINARY_DIR}")

SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "~/Documents/test/myProject/lib/boost_1_65_0")
SET(CMAKE_BOOST_ROOT ${CMAKE_BOOST_ROOT} "~/Documents/test/myProject/lib/boost_1_65_0")
#SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "lib/boost_1_65_0/stage/lib")
include_directories(lib/boost_1_65_0/boost)

FIND_PACKAGE(Boost 1.65.0 COMPONENTS program_options )  
MESSAGE(${Boost_INCLUDE_DIR})

INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})

add_executable (myProject main.cpp)


TARGET_LINK_LIBRARIES( myProject LINK_PUBLIC ${Boost_LIBRARIES} -static-libgcc -static-libstdc++ pthread  )

FIND_PACKAGE 返回:
-- 找不到 Boost
但是 MESSAGE(${Boost_INCLUDE_DIR}) 返回一个目录..

尽管如此，构建还是失败了。正如您所希望看到的那样，我已尝试遵循此相关问题的答案: undefined reference to `boost::program_options::options_description::m_default_line_length'但没有解决问题。

我在 Ubuntu 16.04 上使用 cmake 3.11和 boost 位于 lib/boost_1_65_0

编辑:添加行按照 Tsyvarev 的建议在 find_package() 之前设置(Boost_DEBUG ON)返回以下输出:

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.

您不仅需要安装 header ，还需要安装库。

sudo apt install libboost-program-options-dev 

应该可以解决您的问题。
