Yes, I can set it.

But that's my "problem":

If I set it at my .bashrc (for example) when I share this package other
users must put this directory in their PATH too, and I want to avoid
this if possible because I want this procedure as automatic and
transparent as possible.

If I set PATH on the configure script, Makefile will not find it by
default because this new value for PATH isn't seen by the Makefile.

So, in this situation, I'm unable to give an automatic compiler
selection without asking the user to alter it's PATH.

Of course, I can do it. It's feasible. But I'm looking for a solution
that does not require the user to alter his PATH.
