问题描述
嗨，我正在尝试使用cmake从源代码构建opencv4（在https://thecodinginterface.com/blog/opencv-cpp-vscode/之后）。我将macOS更新到10.15，并安装了最新的xcode。我git克隆了存储库，并创建了如下的构建目录，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
我收到以下错误，似乎正在尝试查找此不存在的路径：
“ / Library / Developer / CommandLinetools / SDKs / MacOSX10.14.sdk / System / Library / Frameworks / OpenGL.framework”
我已经将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？

Imported target "VTK::RenderingOpenGL2" includes non-existent path
"/Library/Developer/CommandLinetools/SDKs/MacOSX10.14.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.

解决方法
下载并安装
用于XCode 12的命令行工具
来自apple developer tools downloads。
它曾经工作过，您可以执行Very long name
Very long …
Very long name|truncatewords:2
并且可以为您执行，但是现在出现错误，提示它找不到包或类似的东西。因此，必须采用这种方法。
