Ok.

That's your problem.  CMake actively refuses to generate makefiles for 
MingW32 if any flavor of the *NIX shell sh is on your path, including 
the sh provided by the MingW32 project.  If you regenerate the makefile, 
it should autodetect MSYS in such a case.

If the MSYS-targeted makefiles are broken (on my slightly non-standard 
MingW32 install with MSYS utilities, this is due to path format issues), 
you should look at my workaround : 
http://public.kitware.com/Bug/view.php?id=7870 .  I have needed this 
workaround for all of CMake 2.6.2, 2.6.4, and 2.8.0, and expect the 
workaround to be needed indefinitely due to complete and utter lack of 
interest in a proper patch.
