Prefix is about the install path, not about the library search path. You
can pass CPPFLAGS='-I/path/to/whatever' LDFLAGS='-L/path/to/whatever' to
configure.  Note that you'll potentially have to change your system
search library path, or LD_LIBRARY_PATH, environment to allow
libc/kernel to find shared libraries.
