I understand that you don't like the hardcoded approach, still this is what made
the configure interface so standardizing that now we discuss it here. There were hardly any
configure scripts that would not provide some of the basic
flags (at least --prefix) and the --enable/--disable syntax for the options.

I understand as well that you want to make it as easy as possible and
it obviously the handling of the OPTION variables requires parsing the CMakeLists.txt and 
the CMakeCache.txt, which would require some more effort than reading only the 
command line shortcut option file. So I would suggest to make 
the mapping

--prefix  -> -DCMAKE_INSTALL_PREFIX
--verbose -> -DCMAKE_VERBOSE_MAKEFILE
--build   -> -DCMAKE_BUILD_TYPE
 
the default mapping which can be changed only if the user supplies a local
configuration file which can only be used to 
extend the shortcut list. The option syntax using --enable-toto...
is in fact a bit longer than -Dtoto= so we may live without it.
And for the help we may rely on ccmake or cmake -i

I think we have extensively discussed the issues and I will
create a feature request such that you will not forget these
suggestions.

Kind regards
