使用CMAGE失败升级到McOS Calalina的OpenCV4 C++构建

嗨，我正在尝试使用cmake从源代码构建opencv4。我将macOS更新到10.15并安装了最新的xcode。我使用git克隆存储库并创建一个构建目录，如下所示，然后尝试配置cmake：

$ mkdir opencv
$ cd opencv
$ git clone https://github.com/opencv/opencv.git
$ cd opencv
$ git checkout tags/4.2.0
$ cd ..
$ git clone https://github.com/opencv/
$ cd opencv_contrib 
$ git checkout tags/4.2.0
$ cd ..


$ cd build_opencv
$ cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=../install \
      -D INSTALL_C_EXAMPLES=ON \
      -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules \
      -D BUILD_EXAMPLES=ON ../opencv

我得到以下错误，它似乎试图找到这个不存在的路径：

/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/OpenGL.framework

我已经将我的mac版本更新为10.15，但它似乎正在MacOSX10.14下搜索路径。我在网上看过，但似乎找不到任何建议

以前，您可以执行xcode select-install，它可以为您执行，但是，现在出现了一个错误，它说找不到包或类似的东西。因此，必须采用这种方法。

安装XCode和安装XCode CLT是两项不同的任务。你两个都做了吗？在升级到Catalina之前，你有没有制作过这个？如果是这样，你需要摆脱旧的安装文件夹，从头开始。您是否检查了openCV的要求以及它支持什么？我在升级到Catalina后安装了Xcode和Xcode CLT。我还检查了需求并安装了必要的先决条件。我只是不知道为什么它还在macOS10.14下寻找路径？您的意思是删除opencv的安装文件夹并重新开始吗？
