How to set default CPPFLAGS and LDFLAGS?

[Pierre Abbat <phma@xxxxxxxxxxxxx>]

I've been writing a program in Kdevelop and I need to package it so that I can 
run it on another computer. It's an XML program, so it needs CPPFLAGS set to 
`pkg-config libxml++-2.6 --cflags` and LDFLAGS similarly. I ran "make dist" 
and copied the tarball to the DFly box and tried to build it. It failed 
trying to find the include file. I untarred it in /tmp on the Linux box and 
got similar errors. I then compared the Makefiles and found that the one in 
the project directory has CPPFLAGS set to a list of include files, while the 
one in /tmp has it set to blank. Configuring with CPPFLAGS and LDFLAGS 
produces a binary that works, and I'm going to add them to the INSTALL 
instructions, but is there a way to set default CPPFLAGS in the configure 
file?
