Cmake 找不到 Boost [英] Cmake doesn't find Boost

问题描述

我正在尝试使用 CMake 配置一个项目，但它无法找到 Boost 库，即使它们位于指定的文件夹中.我已经指定了 Boost_INCLUDE_DIR、Boost_LIBRARYDIR 和 BOOST_ROOT ，但我仍然收到错误消息，指出 CMake 无法找到 Boost.出现这种错误的原因可能是什么?

I'm trying to configure a project using CMake, but it fails to find Boost libraries even though they are in the specified folder. I have specified Boost_INCLUDE_DIR, Boost_LIBRARYDIR and BOOST_ROOT , but I still get an error saying that CMake is not able to find Boost. What could be the reason of such error?

推荐答案

你确定你做的方法正确吗?这个想法是 CMake 自动设置 BOOST_INCLUDE_DIR、BOOST_LIBRARYDIR 和 BOOST_ROOT.在 CMakeLists.txt 中做这样的事情:

Are you sure you are doing it the correct way? The idea is that CMake sets BOOST_INCLUDE_DIR, BOOST_LIBRARYDIR and BOOST_ROOT automatically. Do something like this in CMakeLists.txt:

FIND_PACKAGE(Boost)
IF (Boost_FOUND)
    INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIR})
    ADD_DEFINITIONS( "-DHAS_BOOST" )
ENDIF()

如果 boost 没有安装在默认位置并且不能被 CMake 找到，你可以告诉 CMake 在哪里寻找 boost，如下所示:

If boost is not installed in a default location and can, thus, not be found by CMake, you can tell CMake where to look for boost like this:

SET(CMAKE_INCLUDE_PATH ${CMAKE_INCLUDE_PATH} "C:/win32libs/boost")
SET(CMAKE_LIBRARY_PATH ${CMAKE_LIBRARY_PATH} "C:/win32libs/boost/lib")

当然，这两行必须在CMakeLists.txt中的FIND_PACKAGE(Boost)之前.

Of course, those two lines have to be before the FIND_PACKAGE(Boost) in CMakeLists.txt.
