Subject: [PATCH] Meta: Build zstd correctly to support clang plugins and curl
 8.18.0

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
