Summary of Changes

Hello @liuzicheng1987, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the project's CMake configuration by expanding the search criteria for the msgpack-c library. By adding an alternative name to the find_package command, the build system becomes more robust in locating this dependency, thereby resolving a known issue and ensuring smoother compilation across different environments.

Highlights

• CMake Configuration Update: The CMakeLists.txt file has been updated to improve the discovery of the msgpack-c library.
• Enhanced Package Discovery: The find_package command for msgpack-c now includes msgpackc in its NAMES argument, allowing CMake to locate the library even if it's installed under this alternative name.
• Issue Resolution: This change directly addresses and fixes issue msgpack library name error for ubuntu (24.04 and earlier) #551, likely related to build failures or difficulties in finding the msgpack-c dependency.

Code Review

This pull request adds msgpackc as a possible name for the msgpack-c package in the CMake build script. This improves compatibility with systems where the package is installed under that name. However, the change as-is is incomplete and will likely cause build failures, because the surrounding logic does not account for the different target name (msgpackc) that this package is likely to provide. I've left a comment with a suggestion to make the package finding and linking more robust.
