I've git a project where, at some point in its Makefile, I'm filtering out stuff from a certain directory:
relevant = $(filter-out irrelevant/%,$^)
Now I want to use this in a
VPATH-enabled environment. So the paths of my dependencies in
$^ might not start with
irrelevant any more, but instead something like
../src/irrelevant or similar.
Is there a way to filter-out anything that contains
irrelevant, in any position? I.e. something like the following?
relevant = $(filter-out %irrelevant/%,$^)
This doesn't work, since apparently patterns for
filter-out can contain only a single
% wildcard. I know I could possibly achieve this via a shell invocation, grep or whatever, but I was hoping for some combinations of functions inside the Makefile.
