C include question

[Jason Dusek]

Hi,

I would like to compile some OpenGL stuff on my BSD box. Unfortunately, the GL 
libraries are not in /usr/include/GL - they are in /usr/X11R6/include/GL and my 
C compiler does not see that by default.

One easy way around this is, I think, to just soft link /usr/X11R6/include/* to 
/usr/include/ - but that would defeat the point of seperating the X11 includes 
from the system includes. What is the right way to set this up so that my C 
compiler, no matter which one it is, will always find the GL libraries? Is there 
some kind of 'cc.conf' somewhere in the same sense as there is a 'make.conf'?

I am new to C - in fact this OpenGL stuff is my first exposure to it. I'm sure 
that this is an elementary question, and the only reason that I post it to the 
list is that I am trying to find a way to solve my problem that is more in 
keeping with BSD philosophy than simply moving /usr/X11R6/include into /usr/include.
