我购买了联想 ThinkPad X1 Yoga Gen 7，其特点如下：
32 GiB RAM
CPU：第 12 代英特尔酷睿 i7-1260P x 16
Mesa 英特尔显卡 (ADL GT2)
SSD：2 TB
FHD 摄像头系统，配备 4 个麦克风 3840x2400 显示屏，据我了解，这意味着有一个 MiPi 摄像头*
并安装了 Ubuntu 23.04。
*我无法使用 Linux 或 Windows 检测到相机硬件。通过研究，我发现了“MiPi”。
据我测试，除了内置摄像头外，其他一切都运行良好。我还没能测试麦克风。
这似乎是一个众所周知的问题，类似于这个问题
我尝试按照描述的解决方案操作。不幸的是，由于找不到之前安装的 libcamhal，因此构建 icamerasrc.git 失败。我在我的系统上手动构建和安装的经验并不多，所以我可能犯了一些初学者的错误，任何帮助我都非常感谢。
我尝试的具体内容：
首先，我安装了 Ubuntu 22.04。失败后，我尝试了 Ubuntu 20.04.06，因为有些这种类型的 ThinkPad 是随 Ubuntu 20.04 一起出售的，但再次失败。现在我有 Ubuntu 23.04，我仍在尝试让它工作。
我意识到有些需要的软件包默认情况下没有安装，例如 dkms 和 git。另外，我认为使用 sudo 应该可以，但由于我不知道是什么原因导致的，我尝试以 root 身份安装它。然后我遇到了一些问题，这些问题是由包含空格的路径引起的。我来自 macOS，对此感到很惊讶。无论如何，我消除了不必要的空格。
我最后实际做的是这样的：
sudo su
mkdir -p /media/data/shared/Installer/Linux/avp/Lenovo_ThinkPad_X1_Yoga_Gen_7_internal_Cam/
cd /media/data/shared/Installer/Linux/avp/Lenovo_ThinkPad_X1_Yoga_Gen_7_internal_Cam/

虽然我刚刚安装了 ipu6-camera-hal，但它无法被识别为 libcamhal。这有什么不同吗？我是不是忘了一个重要的步骤？./out 包含以下内容：
out/install/lib/libhal_adaptor.so
out/install/lib/libgsticamerainterface-1.0.so
out/install/lib/ipu_mtl/libcamhal.so
out/install/lib/gstreamer-1.0/libgsticamerasrc.so
out/install/lib/ipu_tgl/libcamhal.so
out/install/lib/ipu_adl/libcamhal.so
这些不是刚刚通过复制安装的库吗/usr/lib？
根据要求，这里有一些输出：
