I'm sure you are aware, but maybe not everyone is, that bmake contains a number of methods to tame META_MODEs enthusiasm for finding things to make a target out-of-date. .MAKE.META.IGNORE_PATHS is the cheapest and generally most useful .MAKE.META.IGNORE_PATTERNS can be more selective and .MAKE.META.IGNORE_FILTER can be expensive, but let you do a lot more. With recent bmake (MAKE_VERSION > 20220126) you can also set target local variables which means you can set say .MAKE.META.IGNORE_PATHS to apply only to a given target. Of course trying to get too clever can end up being counter productive, but the tools are there... --sjghome | help
