I'm marking this as an enhancement, since the code works as designed. I agree it would be nice to allows LIBPATTERNS (and VPATH!) to use target-specific and pattern-specific values.

Right now, though, we don't set up the variable sets properly before doing the lookups for this to happen.

The following makefile illustrates what I regard as a bug in make's library search mechanism. In short .LIBPATTERNS does not work as either a pattern or target dependent variable.

all: dynamic.show static.show

dynamic.%: .LIBPATTERNS = lib%.so lib%.a
static.%: .LIBPATTERNS = lib%.a lib%.so

libs := -lm -lnsl

dynamic.show: $(libs)
static.show: $(libs)

@ echo "LIBPATTERNS and VPATH resolution: $(.LIBPATTERNS) : $@ : $^"
