cmake没有找到boost linux答案

【问题描述】：

我正在尝试使用 Boost 中的 program_options 库。但是，CMake 可以也找不到提升...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。如您所见，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 set(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.

【问题讨论】：

除了文字Could NOT find Boost，应该还有其他人描述这个问题。此外，如果在查找 Boost 时遇到问题，第一步可能是启用 Boost_DEBUG：在 find_package() 调用之前添加行 set(Boost_DEBUG ON) 并显示结果日志。
顺便说一句，您可以使用目标属性设置 C++ 标准，而不是设置 -std=c++0x：cmake.org/cmake/help/v3.1/prop_tgt/CXX_STANDARD.html

【解决方案1】：

您不仅需要安装标头，还需要安装库。

sudo apt install libboost-program-options-dev

应该可以解决您的问题。

【解决方案2】：

CMake/FindBoost 似乎找不到 Boost.ProgramOptions 的库文件。验证您在输出中显示的名称是否确实存在于系统的某个位置，如果存在，请确保 FindBoost 正在查找那里。

【解决方案3】：

它现在正在工作，我认为构建 boost 解决了这个问题：

./bootstrap.sh --prefix=path where to install
./b2 install
