Follow-up Comment #2, bug #56732 (project make):

Thanks for looking at this. Make supports linker flags as dependencies of a
recipe and automatically searches for the .a/.so file using VPATH. See the
relevant section of the manual, 4.5.6 "Directory Search for Link Libraries".

I should have emphasised that this *does* work if it's *not* a pattern rule.
In other words, if you replace this line:


output/% : input/%.in -lAbc


with:


output/example : input/example.in -lAbc


then the recipe works as expected (but, obviously, only for a file named
"example"; unfortunately in my use case I need to build an arbitrary set of
files, i.e. I need a pattern rule).
