Generally Makfile.in will have something like

  LDFLAGS=@LDFLAGS@

and configure, which is generated from configure.in or configure.ac buy
running autoconf, does the substitution when creating Makefile.

so you want to modify configure.(in|ac) to check for the necessary
includes/libs in your custom path, and fall back to the original defaults if
the custom stuff isn't there.
