I know this is a duplicate of bugs http://public.kitware.com/Bug/view.php?id=7313 and http://public.kitware.com/Bug/view.php?id=1527 and the (not longer existing?) http://public.kitware.com/Bug/view.php?id=39. I also know there is no real way of implementing enums, given the way cmake works. But can't the following be done: If for any variable "foo" a variable like "foo_ALLOWED_VALUES" exist, then and UIs (like ccmake, etc.) are allowed to interpret this variable in order to restrict the possible user inputs (yes I know it will still be possible via manual editing and via the command line to set any value). For the syntax of "foo_ALLOWED_VALUES" I'd recommend a extensible format e.g.: "<type>:<type-dependent-data>" Perhaps starting with the two types: enum regexp 1) enum could be something like this: enum:value[|value]* Where value is a allowed value. 2) regexp: could be something like this: regexp:<regexp-type>:<expression> With regexp-type being for example POSIX_BRE for POSIX Basic Regular Expressions, or POSIX_ERE for POSIX Extended Regular Expressions. Maybe later one could add PCRE. expression would be the regular expression that must be matched for a value to be allowed. Why (1)? (2) would not allow for UIs to make choices (e.g. drop down lists), at least not easily.
