Need to update CMakeLists for new LookingGlassCoreSDK rename?

首先检查 vtk/Remote/RenderingLookingGlass 下 LookingGlass 远程模块的 CMake 配置，以及运行 ccmake 时使用的 HoloPlayCore 构建目录。复现该配置，并检查它为何会 checkout 较旧的 commit，或为何要求 HoloPlayCore 而不是 LookingGlassCoreSDK。完成标准是：重命名后的 SDK 能够在 macOS arm64 上完成配置和链接，且无需删除构建目录或使用 symlink 变通方案。

MacOS 12.5.1, M1 arm64, Apple clang version 13.1.6 (clang-1316.0.21.2.5)

Trying to build and getting an interesting error about not finding arm64 symbols - seems this repo is reverting to the previous HEAD which is still linking to an older version of the SDK without the arm64 dylib.

I went into vtk/Remote/RenderingLookingGlass and pulled the latest (55da190d), but on running ccmake it reverts to the previous HEAD at 55dad90.

 Found Git: /usr/bin/git (found version "2.32.1 (Apple Git-133)")

 LookingGlass: Building as a Remote VTK module

 Found HoloPlayCore: /Users/rmlearney/git/vtk/build/HoloPlayCore/HoloPlayCore/dylib/macos/libHoloPlayCore.dylib
 Configuring done

Unfortunately it seems to be ignoring the LookingGlassCoreSDK I cloned into /src - probably because it's looking for HoloPlayCore not LookingGlassCoreSDK which they renamed it to in the interim.

Workaround

1. Generate the build file
2. Delete /build/HoloPlayCore
3. Clone the latest Looking Glass LookingGlassCoreSDK repo into /vtk as advised in this repo's readme.md
4. Make a symlink from /vtk/LookingGlassCoreSDK to /vtk/build/HoloPlayCore
