OSX 10.10 CMake 3.0.2和clang将不会找到本地头 [英] OSX 10.10 CMake 3.0.2 and clang won't find local headers

问题描述

在OSX 10.9上，我在

On OSX 10.9 I had installed a variety of header libraries under

/usr/include
/usr/local/include

今天我对Yosemite做了免费升级，突然一切都停止了。
与Yosemite一起，我也（以前）升级Xcode（注意，我不是使用Xcode编译，而是直接通过命令行进行编译）。

And everything worked fine. Today I did the "free upgrade" to Yosemite, and suddenly everything stopped working. Together with Yosemite, I also (previously) upgraded Xcode (note, I am not compiling using Xcode, but clang directly via command line).

显示包含/ usr / include的CMakeLists.txt。

I have a CMakeLists.txt which clearly includes /usr/include

set(INCLUDE_HEADERS ${INCLUDE_HEADERS}
             /usr/include
             /usr/local/include)
include_directories(SYSTEM ${INCLUDE_HEADERS})

但是，当我尝试编译，我马上得到：

Yet, when I try to compile, I instantly get:

fatal error: 'boost/lexical_cast.hpp' file not found
#include <boost/lexical_cast.hpp>

这里发生了什么？任何人都体验到这一点，甚至知道如何解决呢？
我在10.9版本中工作得很好（我为什么要升级？）
我也可能做错了，因为我注意到cmake升级到3.0.2

What's going on here? Anyone else experience this, or even know how to solve it? Things were working fine in 10.9 (oh why did I upgrade?) I may also be doing something wrong as I noticed that cmake was upgraded to 3.0.2

推荐答案

这种情况的规范方法是：

Canonical way for such situations is:

find_package(boost REQUIRED)
if(Boost_FOUND)
    include_directories(${boost_INCLUDE_DIRS})
endif()

b $ b

它将把BOOST头的路径添加到编译器搜索路径中。

It will add path to the BOOST header into compiler search path.
