In paragraph "7.3 Conditionals that Test Flags" the manual contains the following recommendation


For example, here is how to arrange to use ‘ranlib -t’ to finish marking an archive file up to date:

archive.a: …
ifneq (,$(findstring t,$(MAKEFLAGS)))
...



When the user specifies long or -I<path> options, this piece of code specified above will find 't' when -t was not specified.
E.g.
$ make --no-print-directory -I/tmp
causes MAKEFLAGS to contain '--no-print-directory -I/tmp'.

We can filter out long and -I<path> options with 'filter-out -%'.
E.g.

$(findstring t,$(filter-out -%,$(MAKEFLAGS)))
