Define minimal.
cd Zend && ./buildconf && configure && make
combined with one or two trivial patches to get rid of TSRM dependencies
gives you a standalone library containing only the engine. The result of
configure --disable-all in the php source is the minimum useful thing.

The ones referenced from the current build system's Makefile. I doubt
anybody keeps an extra list. Mind that i.e. TSRM becomes quite small in
non-tsrm mode.

Why? You can always build PHP as a library using --enable-embed (add
"=static" if you want it to be a static library) and use that from your
other project, yes this adds a dependency but avoids lots of build
issues.
