Build Failure on RISC-V: Invalid CMake Package ID for armv8 Architectures

[lyd1992]

When attempting to build Milvus-Lite on a ​RISC-V architecture​ (e.g., SG2042/TH1520) using Conan, the following error occurs during dependency resolution:

Key Observations:

1.The error indicates that the cmake/3.30.5 package is incompatible with the target architecture configuration.
2.Despite building on ​RISC-V (riscv64)​, the error references invalid armv8 architectures (armv8 64 and armv8 8), suggesting a misconfiguration or metadata mismatch in Conan packages.
3.This blocks RISC-V users from resolving dependencies and proceeding with the build.

This description focuses on the core error and its impact on RISC-V builds. Let me know if further adjustments are needed!

I'd like to suggest migrating the project from Conan 1.x to Conan 2.x, especially since Conan 2.x provides better support for using system-installed tools and avoids the automatic download of prebuilt cmake binaries (as discussed in conan-io/conan#1330 (comment)).

This change would allow us to use the system-provided CMake tool on RISC-V platforms, bypassing the need to fetch prebuilt dependencies from remote sources, which is critical for platforms where such prebuilt binaries are unavailable or incompatible.

Would you consider upgrading the Conan recipes and tooling to be compatible with Conan 2.x?

Happy to help with testing or PRs if needed. Thanks!

Since MilvusLite depends on the core module of Milvus, which uses conan 1.x, it needs to be kept consistent to reduce compilation problems
