cmake 突然不适用于更新的 Xcode

Question

我很想解决这个问题。我多年来一直使用 cmake (3.18.2) 和 Xcode，但它突然停止工作。进行以下简单设置：

我制作了一个main.cpp 文件：

#include <iostream>

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

还有以下 CMakeLists.txt 文件：

cmake_minimum_required(VERSION 3.14)
project(untitled)

add_executable(untitled main.cpp)

我制作了一个构建文件并在其中运行：

$ cmake ..

使用的 cmake 来自 anaconda，但自制 cmake 也会发生这种情况。两者都是最新的。

我已经安装了最新的 Xcode 和命令行工具 (v13.0)，因为这开始于无法构建 Xcode 项目，但这似乎与 Xcode。我尝试使用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。我已经在 Xcode 首选项->位置中设置了命令行工具。

这是 Anaconda 重置环境变量的结果，以便使用它们自己的构建工具，而不是 Xcode 命令行工具中的构建工具。这些与使用 Anaconda 提供的 cmake 构建 Xcode 项目兼容，但情况不再如此。您甚至无法从其他来源制作 cmake，因为 Anaconda 也会强制它使用 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（请参阅link）兼容。也许可以通过某种方式使用 Conda 环境来避免对系统的干扰。对我来说，anaconda 干扰你构建你自己的程序违背了它的目的。
