CMake Xcode generator creates a project that cannot build
提问by aaragon
I have a C++ project that uses the CMake build system. I use a MacBook Pro for development, so when I use the terminal everything works like a charm, and I can build my project.
我有一个使用 CMake 构建系统的 C++ 项目。我使用 MacBook Pro 进行开发，所以当我使用终端时，一切都很顺利，我可以构建我的项目。
However, today I found out that I could use Xcode after creating the respective project using the CMake generator:
但是，今天我发现我可以在使用 CMake 生成器创建相应的项目后使用 Xcode：
$> cmake -G Xcode .
It works the project and it looks fine, except for the fact that I can't build anything. It doesn't recognize symbols included from included files. Why is this? It seems as if the CMake environmental variables are not passed to Xcode.
它适用于该项目并且看起来不错，除了我无法构建任何东西的事实。它无法识别包含文件中包含的符号。为什么是这样？似乎 CMake 环境变量没有传递给 Xcode。
How can I fix this?
我怎样才能解决这个问题？

Omit the dot (.) in your command invocation, leaving just cmake -G Xcode. When I first started using CMake, I also was generating Xcode projects that would not build. I was using CMake's interactive wizard UI, which led to a world of hurt. As often happens, using the simplest command is often the way to go. Once I stopped using the wizard and just using the defaults, I got an Xcode project that builds reliably.
在命令调用中省略点 (.)，只留下cmake -G Xcode. 当我第一次开始使用 CMake 时，我还生成了无法构建的 Xcode 项目。我正在使用 CMake 的交互式向导 UI，这导致了一个受伤的世界。正如经常发生的那样，使用最简单的命令通常是可行的方法。一旦我停止使用向导而只使用默认值，我就得到了一个可以可靠构建的 Xcode 项目。
