What do you think very different between

configure --enable-X11
cmake -DENABLE_X11

un*x version of cmake has menu driven UI too
did you try ccmake (note the double 'c')

<joke>
personnally I think the ugliness of GUI app most
of time comes from the GUI concept itself :=))
command line is far more powerful.

I personnally think the OPTION CMake macro is just as good
as AC_ARG_ENABLE is.

May you precise what functionality you miss, from autotools?
(Besides the fact that you have to replace --enable-xxxx with -Dxxxx)
