在 Clion macOS 中通过 CMake 找不到 c++ 头文件和 MacOSX12.1.SDK。但 Xcode 正在工作

Question

我使用的是 macOS Monterey 12.3。 当我尝试在 CLion 上加载 CMAKE 文件时。我收到此错误，它表示找不到 MacOSX12.1.SDK。但我当前的版本是12.3。我不知道为什么它会变成 12.1 版本而不是 12.3。

CMake Warning at /Applications/CLion.app/Contents/bin/cmake/mac/share/cmake-3.21/Modules/Platform/Darwin-Initialize.cmake:303 (message):
Ignoring CMAKE_OSX_SYSROOT value:
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk"
because the directory does not exist.

还有这样的警告：

CMake Error in Build/Debug/_deps/glew-src/CMakeLists.txt:
Imported target "OpenGL::GLU" includes non-existent path 
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/OpenGL.framework"
  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.

同时，当我尝试编译我的程序时，我收到多个 clang 错误，如下所示

include path for libstdc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Werror,-Wstdlibcxx-not-found]

对于这部分，我尝试了首先删除当前版本的 commandLineTools 并执行

Xcode-select --install

修复它的方法。但在我这样做之后，这些错误仍然存在:(

我不确定我对我的 Mac 做了什么，它突然变成这样了。

Cmake 缓存了一个旧的 sdk 路径，该路径在升级 Xcode 后不再存在。

您需要清除cmake缓存，最简单的方法就是删除构建目录。
