cmake 突然无法与更新的 Xcode 一起使用

Question

我非常想解决这个问题。我已经使用cmake(3.18.2)和Xcode多年，但它突然停止工作。进行以下简单的设置:

我创建了一个main.cpp文件:

#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}

和下面的CMakeLists.txt文件:

cmake_minimum_required(VERSION 3.14)
project(untitled)
add_executable(untitled main.cpp)

我创建了一个构建文件，并在其中运行:

$ cmake ..

使用的cmake来自anaconda，但这也发生在自制cmake中。都是最新的。

我已经安装了最新的Xcode和命令行工具(v13.0)，因为这开始无法构建Xcode项目，但这似乎可能是独立的Xcode。我试过用xcode-select --reset,xcode-select -s /Applications/Xcode.app/Contents/Developer/,xcode-select -s /Library/Developer/CommandLineTools等重置Xcode路径。这些都没有帮助。我已经将Xcode中的命令行工具设置为->locations。

这是Anaconda重置环境变量的结果，以便使用他们自己的构建工具，而不是Xcode命令行工具中的工具。这与使用Anaconda提供的cmake构建Xcode项目是兼容的，但现在不再是这种情况了。你甚至不能从其他来源制作cmake，因为Anaconda也会强迫它使用Anaconda的工具。很难以更永久的方式重置所有必要的环境变量或使Anaconda与macOS 10.9 SDK或更高版本(见链接)兼容。也许使用Conda环境可以以某种方式避免对系统的干扰。对我来说，蟒蛇干扰你构建你自己的程序违背了它的目的。
