First, you should require the virtual package "X11" which in turn is
"x11". Then you should query the x11_xxx flags the way packages like gtk
etc. do. See there for details. Then...

Do never change any vendor files, please. All you are allowed to do is
to change the sources of the package you're building. There you can
hack wild, but anything outside is not ok. So, in this case I would add
the above "#define"s to the local Imagefile. This should be sufficient,
shouldn't it?

Then $(DESTDIR) is not respected ;-) Please make sure that
you at least used DESTDIR=$RPM_BUILD_ROOT%{l_prefix}...

For X11 stuff (especially libraries) to work smoothly with other apps, I
would say:

%{l_prefix}/bin
%{l_prefix}/include/X11
%{l_prefix}/lib/X11
%{l_prefix}/man/manX/

I don't think we need a specific imake executable. I should be
sufficient to override the right variables for imake in the package.

I've already looked at it. I've currently no clue how we can
avoid the installation path fixing by forcing X11's Imake to
ProjectRoot=%{l_prefix}. It always complains to me about redifinition of
ProjectRoot. I'm investigating.
