Follow-up Comment #4, bug #62162 (project make):
Thanks, _$$(percent)_ trick makes the job done.
However what is happening is still obscure. For example, here _patsubst_ does
everything correctly
lib1_SRCS := main.c try.c test.c
lib2_SRCS := lib.c api.c
.SECONDEXPANSION:
lib1 lib2: $$(patsubst %.c,%.o,$$($$@_SRCS))
and _lib1_ depends on main.o, try.o and test.o.
Reworking it in static pattern rule fashion results in prerequisites main.c,
try.c and test.c for _lib1_, i.e. patsubst does nothing.
lib1_SRCS := main.c try.c test.c
lib2_SRCS := lib.c api.c
.SECONDEXPANSION:
lib1 lib2: lib% : $$(patsubst %.c,%.o,$$(lib$$*_SRCS))
