I am not sure what you mean by "circumstances". I am trying to
build a C++ library (no libtool) using both local sources and
source files in a common directory for the whole project.
Creating symbolic links to the common sources is no option here.

RedHat 8, Autoconf 2.59, Automake 1.9.6, GNU make 3.80, m4 1.4.3,

See the attachement. To reproduce
tar xpfz example.tar.gz
cd example
autoreconf -i
mkdir build
cd build
../configure
make
You will get an error message saying
gcc: ../output.c: No such file or directory
If you kick out hello_CPPFLAGS from Makefile.am, then some
different build rules are included in the generated Makefile,
VPATH suddenly works, and the error message is gone.
which part of depend2.am are you actually talking about?
See the attached patch. Using this new version VPATH works
for the test case. Probably a very similar patch could be
applied to the libtool and Windows sections in depend2.am.

Yes.
I hope this patch (or maybe an easier version) could be included
into Automake.
Many thanx
