我想在Python项目中使用OpenCV，因此我想安装dlib库.我运行命令pip install dlib，它给了我以下错误:
Installing build dependencies ... done
Getting requirements to build wheel ... done
Preparing metadata (pyproject.toml) ... done
Building wheels for collected packages: dlib
Building wheel for dlib (pyproject.toml) ... error
error: subprocess-exited-with-error
× Building wheel for dlib (pyproject.toml) did not run successfully.
│ exit code: 1
╰─> [6 lines of output]
running bdist_wheel
running build
running build_ext
ERROR: CMake must be installed to build dlib
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for dlib
Failed to build dlib
ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects
由于错误是Cmake must be installed，我安装Cmake使用pip install cmake，但错误仍然存在.所以我也安装了cmake here，但错误仍然存在.
