 No, this is not true

pigeon% cat extconf.rb
require 'mkmf'
$CPPFLAGS += " -I#{idir}" if idir = with_config('tt-include-dir')
create_makefile('tt')
pigeon% 

pigeon% ruby extconf.rb --with-tt-include-dir=/tmp 
creating Makefile
pigeon%
 
pigeon% grep -- -I Makefile
CPPFLAGS = -I. -I$(hdrdir) -I$(srcdir) -I$(prefix)/include    -I/tmp
pigeon%
