AFAICS things work as expected.  See below for comments.

I've never seen --install put in ACLOCAL_AMFLAGS.  Does this cause any
issues?  It could maybe have unwanted effects if triggered on a user
system.

This affects the sources of src/foo.  If you want src/foo2 sources to
also use these flags, then also set src_foo2_CPPFLAGS.

BTW, I'd never use `pwd` here, either -Iinclude or -I$(srcdir)/include
or both (depending on whether include contains files in the build tree
or the source tree or both).
