c++ - Cmake 找不到 boost 库

Question

我在 Mac OS X 上使用以下 CMake 文件，Boost v1.58.0 安装在/usr/local/lib/boost_1_58_0，每次运行 cmake 时都会打印“Could NOT find Boost”。我已经通读了所有有关如何使它正常工作的堆栈溢出帖子，但没有任何效果。有什么我想念的吗？

cmake_minimum_required (VERSION 3.1)
project (HelloWorld)

set (CMAKE_CXX_FLAGS "--std=gnu++11 ${CMAKE_C_FLAGS}")
file (GLOB SOURCE_FILES "source/*.cpp")

set (CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} /usr/local/lib/boost_1_58_0/boost)
set (CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} /usr/local/lib/boost_1_58_0/stage/lib)

set (Boost_NO_BOOST_CMAKE ON)   
set (BOOST_NO_SYSTEM_PATHS ON)
set (BOOST_ROOT /usr/local/lib/boost_1_58_0)
set (BOOST_INCLUDEDIR /usr/local/lib/boost_1_58_0/boost)
set (BOOST_LIBRARYDIR /usr/local/lib/boost_1_58_0/stage/lib)

set (Boost_USE_STATIC_LIBS OFF)
set (Boost_USE_MULTITHREADED ON)
set (Boost_USE_STATIC_RUNTIME OFF)
find_package (Boost 1.58.0 COMPONENTS optional)

if (Boost_FOUND)
    include_directories (${Boost_INCLUDE_DIRS})
    target_link_libraries (helloworld ${Boost_LIBRARIES})
endif ()

include_directories ("source")
add_executable (helloworld ${SOURCE_FILES})

Answer 1

这是错误的，因为 optional 不是库，它只是 header ，因此将其更改为 find_package (Boost 1.58.0) 解决了问题。
