tor may still have some problems picking up include and libs,
not helped by how some systems lay them out, and problems
with --option-style vs env var style. Whichever style if needed,
both should point to the matching locations for whatever installed
ssl set, ie for a private build:

ssl: ./Configure --prefix=/tmp/foo
tor: LDFLAGS -L/tmp/foo/lib and CPPFLAGS -I/tmp/foo/include

You can also build static if you want to run in tiny jails/VMs,
or not be subject to package manager randomness.
