I recall running into many problems with the Automake/Autoconf/libtool/etc.
setup on many projects, including the breaking of a lot of
backwards-compatibility and forward-compatibility. I don't recall anything
specific with GIMP in particular, but it can happen.

Well, I know CMake pretty well, and CMake is much easier to learn than
Autohell. It took me less time to convert Freecell Solver’s build system from
GNU Autotools to CMake than it did to originally autoconfiscate it (and that
was with learning CMake on the fly and without knowing it beforehand). A
different developer on Freenode's ##programming testified a similar experience
with his own project.

Well, I have given many reasons here:

You should have followed and read the link.

This reminds me of Larry Wall's analogy of a ball in a local minima that can
exert some effort into climbing a hill and then reaching an even lower pit
where it will be happier (but thinks that the higher pit is fine).

And I should note that CMake is in no way a hell. I never really liked GNU
Autotools but thought I needed to use it because that was the only sane
solution. Then I discovered CMake and now I'm much happier.  

BTW, we can keep the old Autotools-based setup for the time being in case we
want it because it can co-exist along with the CMake-based one.

I never said I support switching GIMP to Qt.

Well, we can keep the way GIMP does things as it is just fine and just add a
CMake-based build system.
