Copy files in VPATH build

[Jason Curl]

Hello,

When building my package with "./configure" everything works well as 
some datafiles that are required for tests are in the correct place (my 
tests don't need to be installed with "make install"). However, 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:
test.ini: @srcdir@/test.ini
  cp $< $@

./test.ini: @srcdir@/test.ini
  cp $< $@

But the rule:
test2.ini: @srcdir@/test.ini
  cp $< $@

does work, but I don't need to rename the file in the copy, and when not 
using VPATH, it just performs a useless copy.

Any ideas?

Regards,
Jason.
