I use bakefile (http://bakefile.sf.net) for all my
build systems.
It's a great tool since it's used only by developers
to create build systems based on other standard build
systems: MSVC, borland, watcom, etc on win32, autoconf
on unix.
Autoconf is The standard on unix.
So, yes: I'm going to support a lot of platforms. I
don't like CMake and it gave me much more problems
(for example with VTK) than autoconf.

Anyway, this is not a critic to Cmake.
I just want to say that I think that VTK developers
should make easier to interface VTK also to other
build systems (autoconf but also others) in order to
enlarge the user & developer base of VTK; specially
when it requires a very little effort (like writing a
small .pc file to copy during unix installation).

sure !
AC_PATH_VTK([minimum-version], [action-if-found],
[action-if-not-found])

nice article; I posted my comment there.
Anyway give a look also to the comments of autoconf
supporters; they raise some good points...

Thanks,
