W4031 warning

Packager @retail@ blocks left as written in a multi-version build

area: manifest (x4xxx)
fails the build: with --deny-warnings

A Lua or XML file of a converted packager project (compat.packager-keywords) has a --@retail@ (or --@non-retail@) block, and the build covers several flavors. Like the BigWigs packager in a multi-version build, wowlua leaves the block as written, so the code in a --@retail@ block runs on every client, not only on Retail.

Check the game at run time with WOW_PROJECT_ID. A project that releases one game at a time can set compat.per-game, which applies the blocks per flavor.

The compiler reports it like this:

warning[W4031]: `@retail@` blocks are left as written in a multi-version build, like the packager does

 = help: the code runs on every client; use Lua conditions on `WOW_PROJECT_ID` to limit it
