When building my package with "./configure" everything works well as
some datafiles that are required for tests are in the correct place

when I use VPATH builds with "../configure", I don't know how to get
my data files copied from the source to the current build path.
I've just read up on VPATH, and I think gmake is assuming, that
while the datafiles are in the source, the dependencies are
satisfied, even though they aren't in the build directory.
The following rules don't work:
Right. If @srcdir@ is '.', then GNU make will error out here
(non-GNU make would destroy your data, except that it will barf over the
use of $< outside of inference rules first).
test.ini: @srcdir@/test.ini
cp $< $@
./test.ini: @srcdir@/test.ini
cp $< $@
An alternative can be to use AC_CONFIG_LINKS with identical source and
target name for files: the link-or-copy will the only be made if in a
VPATH build. You need Autoconf>= 2.62 and Automake>= 1.11 for this to
work correctly (please set AC_PREREQ and Automake Option to this end,
because the older versions had bugs that could cause source file
removal.) Please report any remaining bugs.
