oelint.var.multiinclude does not support expanding variables

[skycaptain]

Consider meta-montavista-cgx as an example of a pattern where an .inc file is included only when a certain variable is set: https://github.com/MontaVista-OpenSourceTechnology/meta-montavista-cgx/blob/4a74d7d1d956a3320e829eaec14e06036fa0307c/recipes-devtools/libunwind/libunwind_1.6.%25.bbappend

When this pattern is used across multiple bbappends, it triggers the following false positive: warning:oelint.var.multiinclude:'${PN}_mvista.inc' is included multiple times

This warning highlights two issues: First, it appears that this check operates at the global distro level instead of examining includes per recipe. Second, variables are not expanded, which would correctly resolve into unique include filenames.

[priv-kweihmann]

It is true that the include name is not expanded so far, still I don't get how that could result in any sort of warning here.
The linter will group files into logical groups (meaning recipe + matching bbappends), so unless there are multiple bbappends using this scheme that apply to a single recipe, the include statement in question should be parsed only once per group.

Please provide a minimal example on how warning is falsely raised.
