macos - 处理 conan 和 CMake 之间编译器版本的版本不匹配
问题描述
我正在使用 Apple-clang v12 作为 Xcode 安装的默认编译器在 macOS 上进行开发。由于 valgrind 仍然不支持 Big Sur 并且 Apple 版本不支持 Google Sanitizers，我必须通过自制软件手动安装 llvm v11.1 以利用 Google Sanitizers 启用任何内存泄漏检测工具。
不幸的是，这会导致柯南及其与 CMake 和 CLion（我的 IDE）的集成出现一些问题。由于我的依赖项没有使用 clang 而不是 Apple-clang 为我的架构提供二进制文件，因此它们必须在本地构建。不幸的是，柯南和 CMake 在使用两个相互矛盾的错误消息调用它们时出错：

这是在 CLion 的 CMake 输出窗口中看到的输出。第一次调用让 CMake 认为 Apple-clang 是我的编译器，而 conan 被配置为使用 llvm 版本，而在第二步（很可能conan_basic_setup在 my 中调用CMakeLists.txt）选择了正确的 CMake 编译器，但 Conan 最终没有配置文件，因此有一个版本不匹配。
在 CLion 设置中，我已经用 llvm v11.1 编译器覆盖了 c++ 编译器：
正确配置两者以使用 llvm v11.1 编译器的正确解决方案是什么？我个人不想启用CONAN_DISABLE_CHECK_COMPILERCMake 变量，因为不清楚最终将使用哪个编译器来编译依赖项。
以前发布的问题仅建议故意使用我不想要的更高版本：
解决方案
我在您的日志文件中看到的两个包 spdlog 和 fmt 都可用作仅标头配置。因此，如果这些是您唯一的依赖项，您可以简单地将选项设置为仅使用它们标头，这将消除问题，因为没有为这些包构建任何内容。
这样做的一种方法是将设置添加到您使用的配置文件中，添加到选项部分，就像这样
[options]
fmt:header_only=True
spdlog:header_only=True
