这是一个安装 PyQt5 的错误信息，提示了两个问题：1. 目录的权限问题；2. 缺少 PyQt5-Qt5>=5.15.2 这个依赖。你可以尝试使用 sudo -H 来安装 PyQt5，如下所示：

sudo -H python3 -m pip install PyQt5

如果还是出现问题，你可以先尝试解决目录权限问题，然后再重新安装 PyQt5。如果依赖问题仍然存在，你可以考虑更新 pip 或者使用 conda 等其他包管理工具来安装 PyQt5。

这个错误提示是因为你需要先安装CMake来构建dlib。你可以使用以下命令来安装CMake：

sudo apt-get install cmake

或者使用以下命令安装dlib：

pip install dlib --install-option="--no DLIB_USE_CUDA"

这个命令会安装dlib但不包括CUDA支持。
