clang/llvm is dependent on zstd and its cmake will configure/build zstd if it is not available. This is especially the case when the clang plugins libraries are used. Curl 8.18.0 configure fails if zstd is configured by clang first as not all the required zstd libraries will be built by clang's cmake. When testing with clang_plugins enabled the zstd package will be configured before clang to create all the required libraries avoiding later cmake issues between curl 8.18.0 and zstd See https://github.com/llvm/llvm-project/issues/139666
